Operating The Radio; Setting The Volume; Battery Charging - Motorola APX6000 User Manual

4. If the Surveillance Mode switch option is configured, a switch change
only takes effect when the radio is inserted.

Operating the Radio

All operating conditions of the radio, as described in the applicable radio's User
Guide, apply to operating the radio with the APX VA, except that the hand-held
mobile microphone (PTT) is used rather than the radio's push-to-talk (PTT)
switch.

Setting the Volume

• For an APX VA without the optional external speaker — the audio is
routed to the radio speaker and the volume is adjusted using the radio
volume knob.
• For an APX VA with the optional external speaker — audio is routed
through the external speaker and the volume is adjusted using the radio
volume knob.

Battery Charging

One of the functions of the APX VA is to supply power to the radio and charge
the radio's battery. In order for the radio's battery to be charged, the vehicle's
ignition switch must be turned on. However, once the ignition switch is turned
off, the APX VA continues to charge for either a period of up to 30 minutes, or
until the radio's battery is fully charged, whichever comes first. It is important
to prevent the APX VA from discharging the vehicle's battery. The radio may
be turned on or off without affecting the charging cycle. The charger will fully
charge a completely discharged battery in three hours.
While the battery is charging, the charging LED indicator will be illuminated
Solid RED. When battery charging is complete, the charging LED will switch
from Solid RED to Flashing GREEN to Solid GREEN, indicating that charging
is complete. If the charge indicator is not on, the battery is not being charged.
If this occurs, ensure that:
• the radio is properly installed in the APX VA and the Engage Button is
latched,
• the battery is a rechargeable nickel-cadmium, nickel-metal-hydride, or
lithium ion type,
• the battery contacts are clean and free from foreign material, and
• the vehicle's ignition switch is turned on.
