Signal Level; this menu allows the signal levels for selected Radio Cluster Communicator to be viewed.

When entered detailed signalling information is displayed on the two signalling channels used by the

RCC in both directions, as the devices are bi-directional. The received signal strength at the Hub from the

associated RCC is shown as a R01 Hub level, therefore indicating the signal that has been sent from

the RCC to the Hub (the 01 represents the RCC number). The R01 Hub level is updated on every poll

response (30 seconds). The forward signal strength received at an RCC from the Hub is shown as a R01

Hub level, therefore indicating the signal that has been sent from the Hub to the RCC. This level is also

updated on every poll response or immediately when requested by selecting the Manual Update

Option from the menu. Turning the rotary control will change the display between the 2 channels.

Pressing the rotary control switch will revert between the R01 Hub level display and R01 Hub signal

levels for each channel. Signal strengths are shown in dB. The levels displayed are already calculated

taking into account the background level away from the received signal strength, therefore no further

calculations are required.

Front Display Hub/RCC Options Hub / RCC Status Select Desired Device No Signal Level

Ch1 R01 Hub 070dB; this indicates the received signal strength at the Radio Hub from the RCC 01 on

the rst frequency channel used by the system. A level from 0 - 105 is shown to indicate the levels, a

table of which is shown at the end of this section.

Ch2 R01 Hub 070dB; this indicates the received signal strength at the Radio Hub from the RCC 01 on

the second frequency channel used by the system. A level from 0 - 105 is shown to indicate the levels, a

table of which is shown at the end of this section.

Ch1 R01 Hub 070dB; this indicates the forward signal strength received at the RCC 01 from the Radio

Hub on the rst frequency channel used by the system. A level from 0 - 105 is shown to indicate the

levels, a table of which is shown at the end of this section.

Ch2 R01 Hub 070dB; this indicates the forward signal strength received at the RCC 01 from the Radio

Hub on the second frequency channel used by the system. A level from 0 - 105 is shown to indicate the

levels, a table of which is shown at the end of this section.
