VHF Data
Menu Navigation: UNILINK MENU 1/2 > COMM STATUS > COMM
CONTROL > VHF DATA
The VHF DATA option is available if a VHF radio is configured. 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.
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.
