PERIODIC MAINTENANCE SCHEDULE
Routine maintenance is required on the WEATHERPAK
system and its sensors are working and performing within specification. The actual services vary,
based on the sensors installed on your WEATHERPAK
TRx2 should have the compass, air temperature and relative humidity sensors tested to their stated
specifications. (The wind monitor does not require periodic calibration or maintenance). In
addition, the entire WEATHERPAK
conforming variances. For more information, please contact Coastal Environmental Systems'
service department at (800) 488-8291 x157 to arrange maintenance on your WEATHERPAK

TOWER BATTERY LOW VOLTAGE INDICATOR
When the tower batteries voltage drops below 10.7 VDC a flashing "T" will appear in the lower right
corner of the display. Replace with fresh batteries when this occurs. The system will function at
lower voltages, but components will begin to fail, for example, the wind sensor will cease function at
10 volts and the radio will lose 70% of its transmission power at 9 volts.

REPLACING TOWER BATTERIES
WARNING: DO NOT LEAVE BATTERIES IN TOWER WHEN STORING OR SHIPPING TOWER
ASSEMBLY. BATTERIES MAY LEAK CAUSING DAMAGE TO UPPER TOWER SECTION.
The WEATHERPAK
TRx2 has nine alkaline "D" cell batteries, which are located in the upper
section of the tower. The batteries must be replaced with high quality alkaline batteries.
Rechargeable batteries do not perform well in the WEATHERPAK
