Notes:

•If you make an error in the entry process, press CL as often as needed to erase the incorrect data.

•If you enter a frequency that has already been entered, the scanner sounds an error tone and dis- plays LGCôý= and the channel number that has been duplicated. If the dual entry is an error press CL and enter the correct frequency. If the dual entry is inten- tional press ENTER to accept.

•You may replace any frequency by selecting the bank and channel, pressing PGM and entering the new frequency.

Programming Motorola Trunking Systems (UHF-Lo)

You can program the scanner to receive transmissions in the UHF-Lo band (406-512 MHz) of the Motorola trunking system. You can receive these transmissions by checking the trunking system's control channel. You must program the system's base frequency and offset frequency to do this.

Notes:

•Base and offset frequencies vary for each type of trunking system. You can get information about these frequencies for the trunking system you want to scan using www.trunkscanner.com, other Internet sources, or locally-published guidebooks.
