The Nickel-Cadmium Batteries supplied with your telephone must be fully
charged before placing the unit into service.  New batteries or batteries
which have been stored for a long period without use must be charged
overnight using either the Overnight Dual Charger, or the IntelliCharge
Rapid Charger.

Be sure to use genuine Motorola batteries and accessories.  Under its
cellular telephone warranty, Motorola specifically disclaims any
responsibility for damage caused by the use of portable cellular telephone
accessories not manufactured or supplied by Motorola.

WARNING:  Battery may explode if exposed to fire.

CAUTION:  To prevent injuries or burns, do not allow metal objects to

Battery Removal/Replacement

There are two ways to remove and replace your telephone battery - the
Standard Method and the Quick-change Method.

To use the Standard Method,

1.  Turn off your telephone.

2.  Depress the latch button on the rear of the battery and slide the
    battery pack downward until it stops.

3.  Lift the battery clear to remove.

4.  To reinstall, place the battery pack on the unit so that its grooves
    align, and slide upward in the direction of the arrows on the back of
    the telephone, until it clicks into place.

The Quick Change Method allows you to remove your telephone battery at any
time and replace it with a charged spare battery during a telephone call.
This is especially useful if you receive the Lo Bat message or audible
tone during a call.

To use the Quick Change Method,

1.  Advise the party on the other end of the call that you are about to
    change batteries.  You only have 5 seconds to complete this action
    before your call is terminated.

2.  Remove the battery from the phone.

3.  Put on the spare battery.

4.  Press [PWR].  This will return you to your telephone call.  The phone
    will not go through the normal power up cycle as described on Faxback
    Doc. # 46525.

VOX Operation

Voice Operated Transmission (VOX) is a method of conserving battery power
by activating the unit's transmitter only while talking.  In this manner,
your battery's air-time can be greatly extended.

Ask your Cellular System Provider if VOX operation is supported in your
area.  If VOX is not supported in your system, VOX selection will have
no effect.

1.  To select this feature, press [FCN], [1] to access the feature menu.
    Scroll the menu with [*] and [#] until [ _ uOH ] [ _ ModE ] displays.

2.  Use [CLR] to toggle this feature on and off.  See Faxback Doc. # 46529
    for more information on using the Feature Menu.  To exit, press [END].

Low Battery Warning

Low Battery power is indicated by a short dual tone alert repeated
periodically, and the displayed message Lo BAt.  As the battery approaches
discharge, the unit will automatically turn itself off.

Battery Voltage Meter (B V M)

The BVM represents the voltage level of the battery being used.  You can
use this to estimate the amount of battery capacity remaining.

1.  To display the BVM, press [FCN], [!4]. The BVM is displayed as a graph
    following the letter b at the left side of the display.

Variables such as temperature, battery age, and charging conditions may
affect battery voltage.

Internal Charging

With the battery attached, turn the phone off and use either the AC wall
adapter or cigarette lighter adapter to plug into the receptacle on the
bottom of your phone.  A charging LED will light to indicate the charger
is connected.  Note the following for charge times.

Battery Charge Times

Battery Type                   Hours (to 90% Capacity)

NiCd Slim                         6 hours

NiCd Slim Extra Capacity          8 hours

NiCd Standard                    10 hours

NiMH Slim                         7 hours

NiMH Extra Capacity              17 hours

Note:  Operating the phone extends the time required to recharge the
       battery.  The phone will not operate unless the battery is at
       least partially charged.
