Bypassing the charging circuit diode in
- Airtronics RDS 8000 Transmitters
- Note: This Radio does not require a diode
jumper to use the "Sirius" line of chargers through the transmitters charge
jack, however the diode will need to be jumped in order to discharge with our "Supertest"
or "Supertest Pro".

This modification, when properly done, will not affect the operation of your
transmitter. However, do not attempt this procedure
unless you are comfortable with soldering electronic equipment!
1. Remove battery cover and the battery.
2. Remove 8 screws from the rear cover.
3. Open back being very careful not to pull any wires.
As you are opening the case make sure that the antenna assembly
stays with the case front
4. Establish the location of the
diode and solder a small thin (36 AWG) jumper wire across it, as
indicated.* It is important to use 36 AWG wire in
this application because it enables the jumper to function as a Safety Fuse.(*) Be careful not to short the jumper to any
components or circuit board traces in the vicinity of the diode.
(*) Insulated 36 AWG wire is
available from Peak Electronics. Please send us a letter
including a Self Addressed Stamped Envelope and we will get your
wire out to you, free of charge, on the next business day.

5. Reassemble the transmitter, being careful not to pinch
any wires.
6. Install the 8 screws, battery, battery cover, and antenna.
