5. Enter the desired trunking frequency then press ENT to store.
6. To enter additional trunking frequencies as subsequent channels in the same bank, press PROG
or /¥ to access the next open channel then enter the frequencies. (See "Storing Known Frequencies
into Channels").
7. Press SCAN to start scanning.
Notes:
• If you enter a frequency that has already been entered, the scanner sounds an error tone and
displays Dupl. Freq. and the channel number that has been duplicated. If the dual entry is an error
press CLEAR and enter the correct frequency. If the dual entry is intentional press ENT to accept.
• You may replace any frequency by selecting the bank and channel, pressing PROG and entering
the new frequency.
If you make an error in the entry process, press CLEAR as often as needed to erase the incorrect
data.
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.
Note: 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.
If you try to program an offset frequency in the UHF-Hi bands (806-960 MHz), the scanner ignores
the entry.
Follow these steps to program Motorola trunking frequencies in the UHF-Lo band:
1. Press PROG then TRUNK to enter the ID program mode.
2. Press FUNC and press (or hold) /¥ or ¥/ to select the bank.
3. Press MODE and select MOT.
4. Press FUNC then 2. The display indicates Custom Range 1/3 on first line. Base: 406.0000 on the
second line, Offset: 380 on the third line and Step:25kHz on the bottom line.
5. While B in Base blinks, if necessary, press the desired Base frequency with the number keys and
