Planning and Installation
Transceiver Location
In many vehicles the best location for the transceiver unit is the floor
of the trunk compartment; alternate locations are under the dash, under
the front or rear seat and under the rear speaker deck panel. Regardless
of the location choice, be sure the transceiver unit is protected from
dirt and moisture and there is sufficient space around the transceiver
unit to allow airflow and removal. Also allow for adequate clearances for
the control/power cable connector and antenna coaxial cable.
Standard Transceiver Mounting Bracket Installation
Install the standard mounting bracket as follows:
Horizontal Mounting
Step 1 Use the mounting bracket fitted over the transceiver as a
template to determine the mounting screws' (2) locations. Be
sure to first snap the mounting bracket over the transceiver,
since the bracket will flex. Also note the mounting bracket
only fits one way. Be sure the selected mounting location
allows for adequate airflow for the transceiver.
Step 2 Place the mounting bracket on the selected mounting surface.
Mark the locations for the two mounting screws.
Step 3 Center punch the screws' location. Drill 1/8 inch holes for
the mounting screws.
WARNING: Be careful to avoid drilling into the fuel tank or
other vital part of the vehicle.
Step 4 With the transceiver in place under the mounting bracket,
secure the bracket to the mounting surface using the
self-tapping screws and lock washers provided in the fuse
kit.
Vertical Mounting
Follow the same procedures for horizontal mounting except for the two
mounting screws. In place of the mounting screws, use two suitable size
bolts, nuts, and washers (installer supplied). Place a lock washer between
each bolt and the mounting bracket, insert the bolts through the bracket
and holes drilled in mounting surface, and secure with flat washers and
nuts.
Handset Location
Consider the following factors when deciding the handset mounting
location:
The mounting surface must have sufficient strength to support the
handset.
The handset must be within easy reach of the driver during normal
operation of vehicle and should not interfere with the driver's or
passenger's seating or leg space.
The handset must also be within reach of the handset end of the
control/power cable.
Control Unit Mounting Cup Installation
The control unit mounting cup is used to hold the control unit handset.
Adjustable Angle Mounting Bracket Installation (optional)
The adjustable angle mounting bracket provides a convenient means for
mounting the control unit. In a typical application the control unit
hang-up cup mounts directly to the adjustable angle mounting bracket.
Install the adjustable angle mounting bracket as follows:
Step 1 Temporarily position the control unit and mounting bracket to
verify the desired mounting location. Check for clearance and
operating convenience. Using the surface base as a guide,
mark four notes on the transmission hump or other selected
location. The four mounting tabs on the surface base are
somewhat flexible to conform to a curved surface as necessary
Step 2 Using an awl or similar device, open four holes in the carpet
at marked locations. This must be done prior to drilling to
avoid ruining the carpet.
Step 3 Using a 3.2 mm (1/8") bit, drill the four mounting holes and
secure the surface base using the four 8-1/8 x 3/4" tapping
screws provided.
Step 4 Mount the base to the surface base at the desired angle and
securely tighten the angle-adjusting screws.
Antenna Location
The best location for the antenna is at the center of the vehicle roof, or
on glass near the roof. Motorola offers (as an option) a 'thru-the-glass'
type antenna which should be mounted on the vehicle rear window. This type
of antenna should be positioned as high on the window as possible. The
inductive 'button' on the mounting foot must not be crossed by a rear
window defogger element.
Hands-Free Microphone Installation
The mounting position of the Digital HF hands-free microphone within the
vehicle has a definite influence on the performance of the Vehicular
Speaker Phone (V.S.P.) hands-free operation. The microphone should be
mounted either on the sun visor (directly above the driver) or on the
headliner (above the driver). The microphone should never be mounted near
the window or in a location where the road and ambient background noise
would be substantially high (above 85 dB SPL).
The visor clip mounting bracket provides the simplest and most effective
mounting of the hands-free microphone. The clip slides into channels on
the microphone housing, and then clips onto the sun visor. The cable may
then be unobtrusively routed to the Digital HF microphone jack located
near the power cable connector on the DHFA.
Optional External Speaker Installation
The external speaker should be mounted under the dash, on the transmission
hump or in any other suitable location using the mounting bracket supplied
with the speaker assembly. The proposed location must not interfere with
the operation of the vehicle. Also, the speaker must be securely attached
to its mounting bracket. Every effort should be made to avoid locating the
speaker behind a sound absorptive barrier (e.g., facing upward under the
seat or behind a dashboard panel).
CAUTION: Do not install either the speaker or DHFA unsupported to prevent
shifting of the unit which could interfere with the proper
operation of the vehicle. Always use the supplied mounting
hardware.
Control/Power Cable Routing
Many vehicles are equipped with wire troughs in the door sills. If the
vehicle has this feature, use it to provide maximum protection for the
cables and to simplify installation. In vehicles without wiring troughs,
the power cable must be routed where it will be protected from pinching,
sharp edges and crushing. To avoid interference with the vehicle's
electronics, do not run cables above the catalytic converter or near the
vehicle's electronic modules. Use grommets whenever a cable must pass
through a hole in a metal panel. No matter what method of cable routing
is implemented, all in-line connectors must be kept accessible.
The mobile telephone system is designed to operate in negative ground
12-volt electrical systems only.
To minimize electrical noise that interferes with the cellular telephone
operation, be sure to check the condition of the ignition wiring and the
connections to the vehicle battery. All wire connections should be clean
and tight.
Control/Power Cable Installation
The control/power cable provides interconnection of the transceiver,
handset, microphone (if equipped) and the external speaker (if equipped).
Install the control/power cable as follows:
Step 1 Route the control/power as previously specified. Do not pull
on the connector housings while routing the cable.
Step 2 Install and route the antenna coaxial cable as previously
noted. Connect the coaxial cable to the transceiver and to
the antenna.
Step 3 Remove all fuses and tape them to their respective holders.
Step 4 Bolt the black lead(s) of the power/control cable to a
suitable grounded point on the vehicle frame using the ring
lug provided.
Note: Special attention should be given to locating a good vehicle ground.
Optimum radio performance can only be achieved with a ground
connection having a very low resistance. The vehicle frame makes the
best ground, but body structural reinforcement members are also
suitable for grounding purposes. Verify that the connections between
the battery negative terminal, vehicle chassis, and engine block
have low resistance. If it becomes necessary to run the black lead
to the battery, the lead must be fused with a 10-amp fuse.
Step 5 Connect the D-type connector on the power cable, and the
modulator connector on the control cable to the transceiver.
Step 6 Check the power cable fuses and make sure that the correct
sizes and types are supplied.
Step 7 The green/black ignition sense lead of the power cable should
normally be connected to an accessory terminal at the vehicle
fuse block through the green wire of the fuse holder assembly
For proper operation of the convenience on/off feature, the
accessory terminal voltage should go to A+ with the ignition
switch on then go low while cranking the starter, then return
to A+ with the vehicle running. If the ignition sense lead is
left un-terminated the mobile must be turned on with [PWR] on
the handset, and it will always turn on locked. Cut and strip
the green wire connected to the fuse holder (to position the
fuse in the desired location) and connect one end to a
convenient point on the wire coming from the appropriate
accessory terminal using the in-line splice. Connect the
other end to the green/black ignition sense lead on the power
cable, using the blue crimp-style connector.
Step 8 The yellow/black auxiliary alert lead of the power cable
provides a ground for the first five times that the mobile
unit rings. The ground has a fixed duration of one second
for each ring. Although the auxiliary alert line has a 1/2
ampere capacity, it is recommended that the connection to the
auxiliary alert device (such as the vehicle horn, headlights,
etc.) be made through a suitable relay using a 2A slow-blow
fuse for circuit protection. The auxiliary alert feature
must be activated by the telephone user prior to turning off
the car. Ignition sense must be low in order to use the
auxiliary alert feature. If this feature is not desired, the
yellow/black lead may be left un-terminated.
Note: Local regulations may forbid the use of horns and/or
flashing headlights as auxiliary alert devices.
Consequently, the auxiliary alert external signaling
feature should not be used in these areas.
Step 9 Cut and strip the red wire(s) connected to the fuse holder
(to position the fuse in the desired location) and connect
one end to the positive battery terminal using the lug
supplied. Connect the other end to the red A+ wire on the
power cable, using the blue crimp-style connector.
Step 10 Connect the external speaker and microphone connectors
(if equipped) to the speaker and microphone jacks on the
control/power cables. (It is recommended that the plugs not
be installed in an area exposed to excessive moisture.)
Step 11 Carefully inspect all cables and connections; then insert the
10A fuse into the fuse holder on the red lead and the 4A fuse
in the fuse holder on the green/black lead.
