OPTIONS
Internal Battery
An internal battery can be fitted to act as a backup should the ac mains supply fail. This option may be
required when no external dc backup supply is available.
The battery is float charged from the ac supply. If the mains fails, the battery provides a minimum two
hours of operation, at 25
°
C, provided the duty cycle does not exceed 10%. When operating from the
internal battery, the transmit power output is reduced by up to 3 dB.
When the battery option is fitted, link JP2 on the interface module must be correctly set (see ‘Setting
Internal Links’ in the installation chapter).
Rack Mount Option
The base station is normally supplied in a free-standing desktop polymer enclosure. As an option, the
base station's chassis can be fitted in a metal enclosure suitable for 19 inch (483 mm) rack mounting.
Local Monitoring of Transmitted Audio
Normally, transmit and received audio is monitored through the base station's internal loudspeaker; this
allows a base station operator to monitor both sides of voice traffic when remote controllers are being
used. Alternatively, the equipment can be configured so that only receiver audio is monitored through the
loudspeaker.
This facility is enabled by setting link JP1 on the interface module (see ‘Setting Internal Links’ in the
installation chapter).
