Greetings All.. I have one department that uses only a single tone (553.9) opposed to using a two tone setup. I've programmed the Minitor IV pager using a System Type of "Motorola" and codeplug option of "R168 (None)" which gives me fields for 4 sets of two tones and 2 individual tones. IF I enter the single tone in "Call 1" for both "Tone 1" and "Tone 2" I get an error saying that "The tone you entered does not match the spacing rule" although it will leave the "553.9" in the field. When I test the pager using a Kenwood HT thats transmitting both "Tone A" and "Tone B" as "553.9" the pager fails to alert. IF I don't enter anything in for "Call 1-4" but enter in "553.9" for "Call 5" (a single tone field) and test the pager with the Kenwood HT, again the pager doesn't alert.. Any idea what I am doing wrong or whats the proper way to enter a single long tone for a Minitor IV pager? Any assistance will be greatly appreciated...
