Tx Freq - Programs the transmit channel frequency. The digit being changed flashes,
and press the Up/Down buttons to select the desired number for that digit or enter it
using the keypad. Then press the <F2> button to move to the next digit if applicable. If
an invalid frequency is entered, a beep sounds, "Invalid" is briefly displayed, and the
number must be re-entered.
Rx Freq - Programs the receive frequency the same as the preceding Tx Freq.
Sq Adj (Analog Only) - Changes the preset squelch setting on that channel. The default
setting is "0" and values of –7 to +7 can be selected. Increasing this setting toward +7
causes the squelch to open sooner so that weaker signals can be received, and
decreasing it toward –7 causes the opposite to occur.
Note The channel spacing is not set with P25 channels because it is always narrow, and the
squelch cannot be changed because the setting is critical for proper receiver operation.
Chan Spc (Analog Only) - Selects either wide or narrow band channel spacing on
analog channels only. Press the Up/Down buttons to select "Wide" or "Narrow", and
when the desired setting is displayed, store it by pressing the <F2> button.
Note
The next two parameters are programmed only if the radio is programmed for encryption.
Key Select - Selects the encryption key for the channel if applicable. The key storage
location of 0-63 or 1-64 is displayed. If no keys are programmed, "No Keys" is
displayed. Refer to Section 11.2 for more information.
Strapping - Selects the encryption strapping mode for the channel as Clear, Secure, or
Switched. Refer to Section 11.3 for more information.
TG ID (P25 Only) - Selects the talkgroup for the selected channel. Press <F2> to
display the current talkgroup ID and then press <F2> again to enter a different ID from
0-65,535. This number must be entered directly using the DTMF keypad.
Channel Alias - Programs the alias for the channel (DTMF keypad models only). Up to
ten characters can be entered. Press <F2> once to display the current alias and then
press it again to program a new alias. Alphanumeric characters are programmed using
the 0-9 keys. Pressing a key once enters the first letter on the key and then pressing it
successive times enters the letters and the number on the key. For example, press the
"2" key twice to enter "B". Press the <F2> key to move to the next position or press it
twice to enter a space.
Tx Timer - Enables or disables the time-out timer on the current channel. Press the
Up/Down buttons to select the on and off mode, and when the desired setting is
displayed, store it by pressing the <F2> button.

through the following choices. When the desired setting is displayed, store it by
