8.2 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
the programmer when the radio was set up, not to any programming a user can perform. If
a feature is controlled by a front panel option button and that button is not available, it is
probably not available.
If the Keypad Programming option button is available, you can reprogram some
conventional channel parameters. Refer to Section 5.15 for more information.
8.3 Speaking Into Microphone
For best results, hold the radio 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.
8.4 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 background 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 radio. Communication may be improved by moving to
higher ground or away from shielding objects such as tall buildings or hills.
