System Operator Programming
As noted several times in this manual, programming determines the
availability and specific operation of many features. This usually refers to
the programming performed by your system operator when the radio was
set up, not to any programming that you can perform. If a feature is
controlled by a front panel option switch and that switch is not available,
it is probably not available or in a fixed condition. Contact your system
operator for more information on how programmable functions have been
set for your application. If the Keypad Programming option switch is
available, you can reprogram some conventional channel parameters.
Refer to “Keypad Programming” on page 40 for more information.
Speaking Into Microphone
For best results, hold the speaker grille about 1-2 inches from your
mouth and speak at a normal conversational level. Do not shout since it
distorts your voice and does not increase range. Make sure that the PTT
(push-to-talk) switch is pressed before you begin to speak and released as
soon as the message is complete.
Operation At Extended Range
When approaching the limits of radio range, the other party may not
be able to hear your transmissions and there may be an increase in back-
ground noise when messages are received. You may still be out of range
even though you can hear a message. The reason for this is that the signal
you are receiving is usually transmitted at a higher power level than the
one transmitted by your transceiver. Communication may be improved by
moving to higher ground or away from shielding objects such as tall
buildings or hills.
Licensing
A government license is usually required to operate this transceiver
on the air. Your system operator will normally handle the licensing
requirements.
