Tilt the Belt Clip
Insert the Battery Pack
 To remove the battery, turn the radio off and remove any protective cases. Slide the Battery Pack
Latch on the bottom of the radio toward the front
panel while sliding the battery down about 1/2 inch.
Then lift the battery out from the radio while unfolding the Belt Clip.
Do not attempt to open any of the rechargeable Lithium-Ion packs, as they
could explode if accidentally short-circuited.
Low Battery Indication
As the battery discharges during use, the voltage
gradually becomes lower. When the battery voltage
becomes to low, substitute a freshly charged battery
and recharge the depleted pack. The LED indicator
on the top of the radio will blink red when the battery
voltage is low.
Caution
Danger of explosion if battery is replaced with
an incorrect battery. Replace only with the same
or equivalent type.

when not using the Speaker/Microphone.
2) When you press the PTT switch on the
Speaker/Microphone, it disables the internal
microphone, and vice versa.
 If the Busy Channel Lockout feature has been
programmed on a channel, the radio will not transmit when a carrier is present. Instead, the radio
will generate short beep three times and indicate
“ * ERROR *” on the display (16-key and 4key versions). Release the PTT switch and wait
for the channel to be clear of activity.
VX-920/-970 SERIES OPERATING MANUAL
 If CTCSS or Digital Coded Squelch (DCS) Lockout has been programmed on a channel, the radio
can transmit only when there is no carrier being
received or when the carrier being received includes the correct CTCSS tone or DCS code.
Automatic Time-Out Timer
If the selected channel has been programmed for
automatic time-out, you must limit the length of each
transmission. While transmitting, a beep will sound
10 seconds before time-out. Another beep will sound
just before the deadline; the “TX” indicator will disappear and transmission will cease soon thereafter.
To resume transmitting, you must release the PTT
switch and wait for the “penalty timer” to expire.
