It may help to bend the leads to match the width of the socket. This makes it
easier to fit the microcontroller smoothly into the socket.
Test the Controller PCB
Here is the controller test procedure:
1. Connect the IEC power cord to the PR102 and the AC mains (wall socket).
2. Switch on the AC power.
3. Upon power up, the F1 LED will flash a number of times. This is part of the
power-on sequence that reports the revision level of the microcontroller firmware
using flash codes.
4. Measure the DC voltage on TB9. It should be 5V plus or minus 0.25 V.
5. Push the up/down buttons on the controller board, the accompanying LED’s
should light.
6. Push the F1-F4 and TC buttons. The first push should turn the accompanying
LED on, the second will turn it off.
7. Push the AMP A, AMP B, Tape 1 Mon, and Tape 2 Mon buttons. The first push
should turn the accompanying LED on, the second will turn it off.
Test the Remote Control
Install a pair of AAA batteries (not supplied) into remote control battery compartment.
Watch the orientation of the batteries

. Aim the remote control at the IR window. Press
the input selector keys. The front panel LED’s corresponding to the input selector keys
should illuminate.

Take a Break
You’ve reached a significant milestone. I recommend that you take a break.

In earlier versions of the kit, the batteries came pre-installed, with a plastic insulator preventing their
contact with the remote-control electronics. If you have one of those kits, then just pull the insulator as the
batteries will already be in place.
