1.2 General Installation Notes
WARNING:
Disconnect all sources of power (AC and
battery) before installing/removing circuit cards or
servicing the AV-VBM audio panel w/microphone or AV-
VB distributed audio booster.
USE an anti-static wrist strap whenever
handling circuit cards.
STORE circuit cards in static
suppressive packaging.
ENVIRONMENT:
INSTALL the equipment in a clean,
dry environment.
The equipment meets the requirements for operation at
32°F - 120°F (0°C - 49°C) and relative humidity of 85%
RH. However, standby battery life is drastically reduced
at higher temperatures. The recommended room
temperature for installation is 60°F - 86°F (15°C - 27°C).
WIRING:
CHECK that the installation wire sizes are
adequate to deliver the required load current and
maintain compatibility with the specific device operating
voltages.
A secure dedicated ground connection is
required. Although no system is immune to
the effects of lightning strikes, a secure
ground connection will reduce susceptibility.
The use of overhead or outside aerial wiring is
not recommended.
