Here we go...
1. While in Channel Display Mode, select the channel to program.
2. Press the X key to enter Frequency Display Mode.
3. ENTER FREQUENCY: Use the DTMF keypad. The LCD display will reflect your keystrokes.
NOTE: You only have about five seconds between keypresses, or the unit will revert to the previously-stored information.
If your frequency won't "take," you might need to change the Frequency Step Size. You may choose between 5, 10, 12.5, 20, or 25KHz. To change, press and hold the LOW C key for about three seconds - until the current step size is displayed. Use the Channel Selector knob to choose your desired step size. Then press the ENTER button to store it.
4. SET TX OFFSET: Press the LEFT key to toggle between +, -, or NONE (simplex) TX offset.
5. SET TX and RX PL/DPL TONES: There are 42 PL (CTCSS) tones and 84 DPS (DCS) tones available. Unfortunately, they are not "plain English" in nature - you need to use Motorola's conversion chart to find out that, for example, CTCSS "141.3" is "023" for your GP68.
While still in Frequency Display Mode, press and hold the SQL B key for about three seconds, until the display shows the "rPL" information (e.g., "rPL.023"). Use the Channel Selector know to choose your PL/DCS tone for RECEIVE. Of course, if you desire to receive OPEN TONE, leave the "rPL" setting at "000."
Pressing the SQL B key once more gets you to the - you guessed it! - the TRANSMIT tone setting ("tPL.xxx"). Use the Channel Selector knob to choose your tone.
Either press any key to "set" these changes, or wait three seconds, and the GP68 will revert to Frequency Display Mode automatically.
6. Now that you've entered your frequency, set the offset, and entered your tones, SAVE all this information by pressing the ENTER button for three seconds, until the display prompts you with a "P" before your channel number (e.g., "PCh.01"). If that is, indeed, the channel number in which you want this new information stored, simply press the ENTER key once more - momentarily. Your new frequency will show, and you'll still be in Frequency Display mode.
Press the X key to return to Channel Mode display.
To verify what you have just accomplished, be in the Channel Display mode. The X key toggles you between Channel Display and Frequency Display modes. Rotate the Channel Selector knob to the channel you want to check out, then press and hold the ENTER button for three seconds.
You can check out all the settings...then, if no changes were made, simply press the X key momentarily to go back to Channel Mode display. If you made a change, you will need to press the ENTER key for three seconds again - then again momentarily - as in Step 6 above.
