Radio Shack Pro-97
Step-by-Step EDACS Programming Guide
Written by David Cabatu, AH7E
INTRODUCTION
This white page will give you step-by-step instructions to program the Radio Shack Pro-97 scanner to properly receive Ericsson
EDACS type radio systems. Do keep in mind that your scanner can only decode non-digital (in order words, analog only)
transmissions. Also, it is also important that you follow all instructions in order. If something doesn’t go your way, you may have
overlooked something in this list of instructions.

PROGRAMMING INSTRUCTIONS
In this practice programming example, we will program the five (5) channel Waikiki repeater into Bank 0 of your Radio Shack Pro-97
scanner.
First, here are the system frequencies that MUST be entered in LCN (Logical Channel Number) order:
(1) 866.2500
(2) 866.7500
(3) 867.0625
(4) 867.3125
(5) 867.6125
PART A. CLEAR YOUR SCANNERS MEMORY BANKS.
1. Clear the scanners memory by turning your scanner OFF, then ON, and pressing [0] and [1] keys while the main greeting
is showing.
2. After initialization, your scanner should now show a display that defaults to M000 (Bank 0, Channel 00)
PART B. PREPARING THE GROUP ID BANK TO TRACK EDACS
FAILURE TO PROPERLY SET GROUP ID TO EDACS MODE WILL CAUSE YOUR SCANNER TO TRACK IMPROPERLY.
1. Press [PGM], [TRUNK]. The top line of the display changes to ONE of the following:
ID Bank 0 -- If trunking mode is NOT selected.
ID Bank 0-1 ON -- If trunking bank IS selected.
2. Press [MODE] until EDACS appears on the third line. This indicates that the trunking mode is correctly set to EDACS.
3. Press [PGM] to return to frequency programming mode. The display should read P001FM 0.00000, with "P" indicating
that you are in programming mode.
a) If the display reads P00xFM, and 'x' does NOT equal "1", press the UP/DOWN arrow keys to set it accordingly.
b) If the display reads M00xFM, you are in MANUAL mode. Press [PGM] to return to programming mode.
PART C. PROGRAMMING SYSTEM FREQUENCIES
ALL EDACS PROGRAMMING MUST BEGIN IN CHANNEL X01 OF A BANK 'X'.
Using the LCN frequencies above, follow steps 1-5.
1. Enter LCN-1, Press [8] [6] [6] [.] [2] [5] [0] [0] [ENTER].
2. Press [MODE] until the display reads P001ED, indicating that EDACS mode is set for that frequency.
3. Press [PGM] to move to the next channel. Check step B3b above if the display does NOT read P00x (to program LCN-x).
4. Enter the rest of the frequencies in LCN order, following steps 1 through 3 above.
5. Press [SCAN] to begin trunk tracking.
If your scanner is programmed correctly, active talkgroup IDs will be displayed in decimal format until you assign a text tag to it.
If you don't hear anything after a few minutes of listening, the scanner just hasn't found the control channel. You can press [SCAN]
to quicken the process. Also, make sure that you do not lock out the control channel.
To program other banks, follow all steps in Parts B and C. The number of steps will vary depending on how many channels need to
be programmed in that bank.
