3. With the transceiver pack turned OFF, plug one end of the programming cable
into the transceiver pack programming jack. See Figure 15.
4. Plug the other end of the programming cable into the base station programming
jack. See Figure 15.
5. Turn the transceiver pack ON. Audible tones will be heard in the compact
earset earphone, indicating that programming is complete.
6. If the transceiver pack is used in a 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 13.
c. Audible tones will be heard in the compact earset 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 16.
Figure 16.
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.
