Relative humidity value is for data logging and is not used in fix computations.
(35) Verify entry on display and press enter (E) key .
NOTE
Variables 1 thru 4 are defined by user and may be used to record variable
conditions at site, such as wind speed, cloud cover or other problem
areas.
Variables 1 thru 4 may range between 0 and 16,383. User
variables are used for data logging and are not used in fix computations.
(36) Enter variable parameters 1 through 4.

memory.
If unit has been in operation at previous site and has been transported in
the power on/standby mode on internal batteries, alert data is still
available in processor memory.
Alert data may be entered from any data
tape cassette acquired at any site within 90 days. An alarm will sound
if alert data is older than 90 days or if orbital parameters for fewer

Before loading alert data, be sure that
that GMT date and time have been correctly entered.
