VHF DATA
The VHF DATA page allows the user to enable or disable the
individual DSPs and provides access to the VHF Frequency
(FREQUENCIES) page. On the COMM CONTROL page press VHF
DATA, LSK [2L] to access the VHF DATA page.
NOTE: The FREQUENCIES prompt is only displayed while the VHF
link is operating in POA (mode).
Pressing the LSK adjacent to each DSP toggles the network status
between DISABLED and ENABLED. In the ENABLED status, UniLink
will communicate with the service provider as appropriate. The
DISABLED status prohibits communications with the provider. If all
Service Providers are selected to DISABLED, the VHF status
displayed on the COMM STATUS page will reflect NOCOMM/NO
DSP.
To resolve a VHF NOCOMM problem:
1. On the VHF DATA page, ensure VHF STATE is not set to
SUSPEND.
2. Press LINK TEST SEND. This will initiate a link test to reestablish
VHF communications.
Communications should be reestablished within approximately one
minute and the NOCOMM advisory should no longer be displayed.
If NOCOMM continues to be displayed, this may indicate an
equipment or VHF system network failure not associated with
incorrect frequency usage.
