1. INTRODUCTION
The MCT-211 is a miniature waterproof wrist-worn transmitter,
designed for use in advanced, high security alarm and remote control
systems. Transmission is initiated by depressing the pushbutton at
the center of the unit. When activated, the transmitter sends out a 24-
bit ID code and an alarm code, both identifiable by compatible
PowerCode type receivers. The ID code assigned to each transmitter
is unique and virtually impossible to reproduce.
All MCT-211 units are supplied with a wrist band, to be worn like a
regular watch.
An LED lights during transmission, indicating that the battery voltage
exceeds 2.4 V approximately.
If the LED does not light (in 315 & 433 MHz versions) or flashes (in
868.95 MHz version) during transmission, the battery must be
replaced immediately. In addition, a transmitter in which the battery is
low will automatically add a "low battery" code to its outgoing digital
message. Compatible receivers are designed to identify this code and
operate audible, visual or other alert devices.

3. TESTING AND MAINTENANCE

3.1 Testing a New Unit
Since the MCT-211 is supplied with the battery already installed, the
unit is practically ready to be tested.
A. "Teach" the target receiver the ID code of the tested transmitter,
as instructed in the target receiver's installation manual.
B. Stand 3 m (10 ft) away from a target receiver and operate the
MCT-211 by depressing its transmit pushbutton. Verify that the
transmitter LED lights, indicating good battery condition.

Note: The LED will light for 2 seconds even if you press the button
for a shorter duration.
C. Observe that the receiver's LED lights, and make sure that the
receiver reacts as programmed.
D. Operate the transmitter from various locations within the area
covered by the target receiver to determine "dead" locations,
where transmission is blocked by walls and large objects, or
affected by structural materials.
Note: If dead/marginal zones are a problem, relocating the
receiver may improve the performance.

3.2 Battery Replacement

The original battery supplied with the transmitter can be used for 3
years (for single transmission per day). Battery replacement will
therefore be needed very rarely.
Make sure that the rubber ring that serves as a seal is in place
around the rim of the base. If it comes loose, save it for later use
together with the screws.
Note: The strap pivots are seated in open grooves at the two edges of
the base. If you put the base on the table "on its back", the pivots and
the two sections of the strap will remain in place.
Upon removing the cover, the top side of the transmitter module is
viewed (Fig. 3). The battery clip and battery will be out of sight - they are
both located on the bottom (hidden) side of the module.
A. Grasp the transmit switch, lift the transmitter module out of the
base and turn it over. The bottom side can now be viewed.
B. Slide the old battery from under the clip in the opposite direction to
the arrow shown in Figure 4.
C. Hold the 3-volt replacement battery (type CR-2025 or equi- valent)
with the positive (+) side up. Slide the battery all the way in under
the battery clip until it stops.
D. Turn the transmitter module over and briefly press the transmit switch
(Fig. 3). The on-board LED should light brightly for 2 seconds.
E. Align the positioning dent (Figure 3) with the guide pin in the base
and place the module within the base. Then close the case as
instructed in Para. 3.5 below.

3.3 Opening the Case

A. Put the transmitter face down.
B. Loosen and remove the 4 screws shown in Figure 2. Take care
not to lose the screws.
C. Turn the transmitter over. Hold the base between the fingers of
one hand, and pull the cover off.
D. Make sure that the rubber ring that serves as a seal is in place
around the rim of the base. If it comes loose, save it for later use
together with the screws.
Note: The strap pivots are seated in open grooves at the two
edges of the base. If you put the base on the table "on its back",
the pivots and the two sections of the strap will remain in place.
Upon removing the cover, the top side of the transmitter module is
viewed (Fig. 3). The battery clip and battery will be out of sight - they are
both located on the bottom (hidden) side of the module.

3.4 Replacing the Battery

A. Grasp the transmit switch, lift the transmitter module out of the
base and turn it over. The bottom side can now be viewed.
B. Slide the old battery from under the clip in the opposite direction to
the arrow shown in Figure 4.
C. Hold the 3-volt replacement battery (type CR-2025 or equivalent) with
the positive (+) side up. Slide the battery all the way in under the
battery clip until it stops.
D. Turn the transmitter module over and briefly press the transmit switch
(Fig. 3). The on-board LED should light brightly for 2 seconds.
E. Align the positioning dent (Figure 3) with the guide pin in
and place the module within the base. Then close the case as
instructed in Para. 3.5 below.
