with DTMF encoders but do have CTCSS, Tone
Squelch can be used to make a quiet channel on
a crowded frequency.
Earphones
&
Speaker/Mics
Using the lowest possible volume setting
minimizes current drain while receiving. You
can hold the transceiver up to your ear and re-
duce the volume to minimum, but it may be
more convenient to use an earphone, speaker/-
mic or the
Earpiece/Mic, and keep
the transceiver clipped to your belt, particularly
in noisy environments.
Battery Care
As the battery discharges, the voltage drop
(when transmitting) increases. When battery
voltage drops to around
4.0 volts, flashes, in-
dicating the batteries should be replaced or re-
charged.
As battery voltage drops further, the
transceiver shuts off.
If
using rechargeable batteries, switch the
transceiver off and recharge or replace the bat-
tery as soon as the indicator begins to blink. Try
to avoid recharging Ni-Cd batteries often with
little use between charges, as that can degrade
the charge capacity and useful life of the cells.
Since it is hard to know exactly when the charge
will run out, you may want to carry an extra,
fully-charged pack with you to avoid having
operation interrupted.
