INSTALLATION ADJUSTMENTS

The Installation Adjustment Mode, which can be accessed only through use of a four-digit code
(Access Code #2), permits the MT 5500 to be set up properly for best performance in a given oper-
ational environment. Various options permit setting the unit for proper operation in conjunction with
other walk-through units or for dealing with typical operation problems.
Default settings, preset at the factory, are indicated below for each of the functions in this mode. Use
the + or - touchpads to regulate any of the functions.
To access the Installation Adjustment Mode for the first time, press the ACCESS touchpad and enter
the factory preset code of 5678. Functions to be set will be displayed in the following sequence:
Pressing ACCESS will scroll through these selections:
5.1 RECEIVER BALANCE
RX BALANCE will be displayed, indicating the balance of the receiving antenna. A number less than
50 is acceptable. If the number is greater, check the areas around the detector for large metal
objects. If such objects are found, either move the object(s) or move the detector to eliminate a
potential problem.
Press ACCESS for next adjustment or OPERATE to return to normal operation.
5.2 TONE
The alarm tone is initially set at a median level. Through use of the + and - touchpads the tone level
can be raised or lowered. A corresponding number (1 to 9 ) will be displayed on the LCD panel and
the tone that has been selected will be heard. Each tone level number contains tones of two differ-
ent pitches, low and high. The pitch of the desired tone is used to indicate left side or right side
direction. When the desired tone is reached, press ACCESS to select the next adjustment or press
OPERATE to return to normal operation.
5.3 SYNCHRONIZATION
Preset factory option is MASTER. See Multiple Unit Operation in Section 11.3 for directions on prop-
er use of this option when it is necessary.
MASTER enables the unit to operate on its own internally generated synchronization from the
power line.
SLAVE synchronizes the unit to the signal received from another MT 5500 on the Sync terminal (on
the lower center of the Controller Circuit Board).
Press ACCESS for next adjustment or OPERATE to return to normal operation.
5.4 CHANNEL
This feature will allow multiple units to operate in close proximity. It is recommended that when two
(2) MT 5500 units are operated in close proximity that Channels 1 and 2 are used. If three (3) or
more MT 5500 units are operated in close proximity, use Channels 1, 2 and 3. (Section 11.3). Press
ACCESS for next adjustment or OPERATE to return to normal operation.
5.5 VIDEO FILTER
This filter permits the unit to function effectively in proximity with video terminals of all types, com-
puter, broadcast, closed circuit, etc. This filter may not apply to certain non-synchronous noise
