WarnIng! Fcc rF ExposurE rEquIrEmEnts
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away from
your mouth and keep the antenna at least 2 inches (5 cm) away from your head and body.
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to-
Talk congurations.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting more than
50% of the time can cause FCC RF exposure compliance requirements to be exceeded. To keep the Body
Worn conguration with the Vertex Standard CLIP-20 belt-clip, reduce the maximum operating duty
cycle still more.
The radio is transmitting when the red LED on the top of the radio is illuminated. You can cause the ra-
dio to transmit by pressing the P-T-T button.

tx savE dIsaBlE
Press (or press and hold) the assigned Programmable
key to disable the Transmit Battery Saver, if you are
operating in a location where high power is almost
always needed.
The Transmit Battery Saver helps extend battery life
by reducing transmit power when a very strong signal
from an apparently nearby station is being received.
Under some circumstances, though, your hand-held
radio may not be heard well at the other end of the
communication path, and high power may be neces-
sary at all times.
locK
Press (or press and hold) the assigned Programmable
key to lock the CH Selector knob, Programmable
keys, and PTT switch. The precise lockout congura-
tion is programmed by your Vertex Standard Dealer.

locK
In order to prevent accidental channel change or
inadvertent transmission, various aspects of the
CH Selector knob, Programmable keys, and PTT
switch may be locked.
The precise lockout conguration is programmed by
your Dealer.
To locked out the key locking, turn the radio off.
Now, press and hold the PTT and SIDE-2 key while
turning the radio on again.
To cancel locking, repeat this process.
artstm
(auto rangE transpond sYstEm)
This system is designed to inform you when you and
another ARTSTM-equipped station are within commu-
nication range.
During ARTSTM operation, when the radio receives
an incoming ARTSTM signal, a short beep will sound.
If you move out of range for more than two minutes,
your radio senses that no signal has been received;
a short triple-beep will sound. If you subsequently
move back into communication range, as soon as the
other station transmits, a short beep will sound again.
artsIItm
(auto rangE transpond sYstEm)
The ARTSIITM system is enhanced feature of the
ARTSTM which can be nding out the communication
range of the radio individually by using the MDC-
1200® Encode/Decoder.
