GETTING STARTED
Install & Remove the Battery
Insert the battery pack so that the two bottom protrusions fit into the holes
and then close the battery so the battery clip clicks closed.
To remove the battery, lift up the clip at the top back of the radio to release
the battery.
Install & Remove the Antenna
Connect the rubber antenna to the top antenna socket by inserting the plug
and turning in a clockwise direction. Make sure that the antenna is fully con-
nected until tight.
NOTE: That the radio requires the antenna to function. Do not transmit
without an antenna connected as this could damage the radio.
Install & Remove the headset / programming cable
Open the side headset speaker / MIC / USB port cover and then plug in the
accessory firmly into the side jack.
If you want to remove the accessory, unplug it gently and close the cover.
Charging the Battery
y
When the battery capacity runs low, the radio will announce “Please
change the battery”.
y
There are 2 ways to recharge the radio:
Using desktop cradle:
Plug the cable from mains adaptor into the back
of the desktop cradle and then insert the radio in the cradle. Light on the
cradle will show RED when charging and GREEN when full.
Direct plug in: Plug in the cable for the mains adaptor into the side micro
USB charge socket. Light on the radio will show RED when charging and
NO Light when full.
Only use the supplied charging adaptors to recharge the radio and battery.
NOTE:
That the battery can be recharged separately from the radio using
the desktop charger.
CHARGE TIME is approximately 3 hours from flat to full.
OPERATING TIME is approximately 25 hours with a fully charged battery if
used typically on a 5:5:90 duty cycle on 0.5W power.
NOTE:
1. Make sure the radio is switched off during charging or the charging time
will be longer and number of possible battery charge cycles reduced.
2. Li-ion batteries do not have memory so they can be recharged at any
time. There are a limited number of charge cycles that the battery can
handle, typically 500-700 times. To get the maximum use of the battery,
only recharge when getting flat. If an almost full battery is recharged,
the charging cycles are not optimized.
