5.1 Manual Test Mode

The GSM Motorola T189 is equipped with a manual test mode capability. This capability allows
service personnel to take control of the unit, and by entering certain keypad commands, make the unit
performs desired functions.
To enter the manual test command mode, a GSM / DCS mini test sim (Part No 8102430Z04) must be
used.
The test sim is inserted into the SIM slot in the side of the phone (See figure 6.1), the battery should
then be inserted and the unit powered on. The # button should then be pressed for approximately 3
second until 'test' appears on the display, and the correct commands must then be followed.
