3. With the transceiver pack turned OFF, plug one end of the
programming cable into the transceiver pack programming jack. See
Figure 17.
4. Plug the other end of the programming cable into the base station
programming jack. See Figure 17.
5. Turn the transceiver pack ON. Audible tones will be heard in the
headset earphone, indicating that programming is complete.
6. If the transceiver pack is used in a dual-lane cross-lane system, the
transceiver pack must also be programmed for cross-lane operation:
a. Turn the transceiver pack OFF.
b. While pressing and holding
both
T1 and T2 on the transceiver
pack, turn the transceiver pack ON. Hold all three switches for at
least 5 seconds. See Figure 15.
c. Audible tones will be heard in the headset earphone, indicating
that programming is complete.
7. Repeat Steps 1 through 6 to program the rest of the transceiver packs.
The transceiver pack is now programmed to the same channel as the base
station. If interference continues to occur, repeat the channel
programming procedure. After seven channel changes, the original
channel will again be encountered. If none of the channels is
interference-free, contact your local 3M InTouch Products dealer.
Outdoors, sound travels best at night when air temperatures are cooler and
background noise is reduced. To allow you to reduce the volume of the
menu sign speaker to a lower, pre-set nighttime level, the base station has
a VOLUME DAY/NIGHT switch. See Figure 18.
Figure 18.
Normally, the VOLUME DAY/NIGHT switch is always left in the DAY
position.
However, if local ordinances require quieter nighttime operation of the
menu sign, move the VOLUME DAY/NIGHT switch to the NIGHT
position.
