the belt pack programming jack. See Figure 19.

programming jack. See Figure 19.
6. Audible tones will be heard in the headset earpiece, indicating that
programming is complete.
7. Repeat Steps 1 through 6 to program the rest of the belt packs.
The belt 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 20.
Figure 20.
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.
