4. The display will show that it is searching for the generator and
the yellow LED may flash occasionally as it receives data from
the generator transceiver. This is due to the unit searching for
the correct channel.
5. Once the generator is found, the radio link is now established
and the settings will be remembered next time the display unit
is turned on. If the generator is not found, an error message
will briefly be shown, and the yellow LED will flash at one (1)
second intervals to indicate the display unit was unable to find
the generator. Repeat steps 2 and 3 with the Display closer to
the generator.
6. If the generator is not talking to it’s transceiver, but the radios
are talking to each other, this will be indicated by an appropri-
ate alarm which will be displayed after a 30 second period.
Check the wiring and connection to the generator.
7. Place the display at the preferred location. Do not permanently
mount it yet.
8. Plug the wall transformer into the display so as not to use
up the batteries. Familiarize personnel with the radio menu
(by reading the manual in conjunction with operating the
display).
9. Monitor the signal strength by looking at the display of signal
strength bars on the display (Figure 11). Note that it takes
a few seconds for the display to update the signal strength
display. Relocate the display if the signal strength is poor or
non-existent.
10. Mount the display using the holes on the back to hang onto
two suitably sized fixing screws in the drywall 2¼ inches
apart. It should be vertically mounted on a wall BETWEEN
studs for maximum signal strength (Figure 9).

11. Once a link is established, the display will "remember" it's
own generator and will not need to search for it again after it
is turned off and back on. If the battery is ever disconnected
at the generator end, the generator will search for the display
when the battery is reconnected. It is important that the dis-
play is powered from the wall transformer at this time and
not it's internal battery. This is because the display would
normally be in sleep mode when powered from it's battery
and the generator would be unable to find it.
12. Set the time and date into the clock, use the instructions
given in the "Time and Date Menu" section. The time and date
will be remembered even if the battery goes dead. There is a
separate, replaceable 10 year battery for this function.
13. The communications LED will light solid to show data is being
received. A flashing LED indicates the unit was unable to find
the generator.
14. Set an exercise day and time now (see "Exercise Menu" sec-
tion).
THE COMMUNICATIONS LED
The communications LED will light solid to show data is being
received. If the LED flashes at regular one (1) second intervals, it
indicates the unit was unable to find the generator. Irregular flash-
ing is an indication of poorer reception.
GENERATOR COMMUNICATIONS
The transceiver requests data from the generator every two (2)
seconds and this is stored inside the transceiver locally. The data
is relayed to the base station over the radio link every time it is
requested by the display about every two (2) seconds. When on
battery power, the data is only requested every minute to con-
serve batteries. If the generator is not talking to it’s transceiver,
but the radios are talking to each other, this will be indicated by
an appropriate alarm which will be displayed after a seven (7)
second period (Figure 10). Check the wiring and connection to
the generator.

CONTRAST ADJUSTMENT 
The display contrast can be adjusted from the “Settings” menu.
Any changes to the contrast setting will be remembered even if
power is removed from the display.
BACKLIGHT 
The backlight is lit whenever a key is pressed. It will remain lit for
20 seconds if there are no further key presses. If an alarm occurs,
the backlight will flash at a one (1) second rate (not if battery
powered).
