The following reference table identifies the indicators that correspond to each position in F73 mask
syntax. Use this table when entering or reviewing MASK settings. Table also provides the factory
settings for a unit with one or two GPS receivers:
Note: Alarm Mask does not provide an setting for LED BLINK, which is not an alarm setting. Also, the
Rb Oscillator Alarm Enabled setting is available even if a Rubidium oscillator is not present.
To change the Alarm Enabled setting for each indicator, enter to E (Enable), D (Disable), or “-”
(Unchanged) using this format:
F73<S>MASK<SEP><123456789ABCDE><CR>
For example, to enter new mask settings, enter:
F73 MASK DDE-EEEEEEEEEE
XLi replies:
OK
To verify the changes, enter:
F73 MASK
XLi replies:
F73 MASK DDE-EEEEEEEEEE
