TEST MODE ACCESS:
INSTALLED MOBILE PHONES AND TRANSPORTABLE MODELS
To enter test mode on units with software version 85 and higher you must short pins 20 and 21 of the
transceiver data connector. An RS232 break out box is useful for this, or construct a test mode adapter
from standard Radio Shack parts.
For MINI TR or Silver Mini Tac transceivers (smaller data connector) you can either short pins 9 and
14 or simply use a paper clip to short the hands free microphone connector.
HAND HELD PORTABLE MODELS:
There are two basic types of Motorola portable phones, the Micro-Tac series "Flip" phones, and the
larger 8000 and Ultra Classic phones. Certain newer Motorola and Pioneer badged Micro-Tac phones
do not have a "flip", but follow the same procedure as the Micro-Tac.
8000 & ULTRA CLASSIC SERIES:
If you have an 8000 series phone determine the "type" before trying to enter test mode. On the back of
the phone, or on the bottom in certain older models, locate the F09... number this is the series number.
If the FOURTH digit of this number is a "D" you CAN NOT program the unit through test mode, a
Motorola RTL4154/RTL4153 programmer is required to make any changes to this unit.
Having determined that you do not have a "D" series phone the following procedure is used to access
test mode:
Remove the battery from the phone and locate the 12 contacts at the top near the antenna connector.
These contacts are numbered 1 through 12 from top left through bottom right. Pin 6, top right, is the
Manual Test Mode Pin. You must ground this pin while powering up the phone. Pin 7 (lower left) or
the antenna connector should be used for ground. Follow one of these procedures to gain access to pin
6:
1. The top section of the battery that covers the contacts contains nothing but air. By careful
measuring you can drill a small hole in the battery to gain access to pin 6, alternately simply cut the
top off the
battery with a hack saw. Having gained access use a paper clip to short pin six to the antenna
connector ground while powering up the phone.
2. If you do not want to "destroy" a battery you can apply an external 7.5 volts to the + and -
connectors at the bottom of the phone, ground pin 6 while powering up the phone as above.
3. You can also try soldering or jamming a small jumper between pins 6 and 7 (top right to lower
left), or between pin 6 and the antenna connector housing ground. Carefully replace the battery and
power up the phone. Use caution with this method not to short out any other pin.
4. A cigarette lighter adapter, if you have one, also makes a great test mode adapter as it can be
disassembled to give you easier access to pin 6. Many are pre marked, or even have holes in the right
location. This is because they are often stamped from the same mold that the manufacturer
uses for making hands free adapter kits and these kits require access to the phone's connectors.
