Press ENTER when done.
5.2.1.10.7 CONFIG: Misc  Warm-Up
High-Stab Reference Warm-Up Delay:
Enabled (None,Enable) ()
The High-Stability Reference Module contains an oven for its crystal. During the short time it
takes for the oven and crystal to come up to temperature, frequency accuracy is not
guaranteed.
Use this menu to select a Warm-up Delay that executes upon power-up. This delay is calculated
by the modem and is based on temperature and the amount of time the unit was turned off.
This is much more important at L-Band (950-2000 MHz) than at 50-180 MHz, where the 10 MHz
reference may also be used for RF conversion equipment.
Once this feature is enabled and the modem is powered up, a Warm-Up Delay Countdown is
activated during which time the Tx is suppressed. This countdown displays in decremented
fashion as shown in this example:

High-Stability Ref warming up: 045 sec
Press the CLEAR key to bypass this warm-up period as needed.
5.2.1.10.8 CONFIG: Misc  Stats (Statistics)
Link Statistics Logging Interval:
10 minutes (00 to 90) ()
The Logging Interval is the period over which performance statistics are to be measured. Use the
▲▼ arrow keys either to set this interval as 00 to disable the feature (i.e., no logging), or to
select a logging interval, in 10-minute increments, from 10 through 90 minutes. Press ENTER
when done.
