Vertex Standard VX-900 ユーザーズマニュアル

r

To install the battery, hold the transceiver with

your left hand, so your palm is over the speaker

and your thumb is on the top of the belt clip. Care-

fully mate the battery four insertion slots with

their corresponding alignment tabs on the trans-

ceiver case, while tilting the Belt Clip outward.

Proper alignment occurs with the battery pack

offset about 1/2 inch from the top edge of the bat-

tery compartment.

r

Guide the pack to the tabs with a slight inward

pressure, then slide the battery pack upward, un-

til it locks in place with a “Click.”

To remove the battery, turn the radio off and re-

move 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.

As the battery discharges during use, the voltage

gradually becomes lower. When the battery voltage
reaches 6.0 volts, it is time to 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 (6 Volts or lower).
