Maintenance
FTR264 requires no special maintenance, but the battery needs to be changed whenever the ”Change
Battery” indicator starts blinking. Battery life depends on the used transmit interval. Ambient
temperature also has an effect on attained battery life, temperature extremes shorten the battery life.
The following diagram can be used to estimate battery life with different transmit intervals.
With long transmit intervals the battery life approaches the shelf-life of the battery. Along with ambient
temperature the battery life is also affected by the age, quality, brand and manufacturer of the battery.
The enclosure can be cleaned externally by using soft cloth moistened with water and mild detergent or
isopropanol.
