TriMark 500-1300 e-ASK, Manual

Page: 10 / 36

The e-ASK Fob is designed to use commonly available CR2032
batteries. Estimated end customer normal use should have an expected
life of 2 years for the fob battery. Variances across commercial battery
manufacturers and operating environment conditions will result in
deviations from the expected battery life. The following guidelines
should be followed to optimize fob battery life and system performance.
The e-ASK fobs are designed to operate in a low power or “sleep”
mode. The fobs electronics will “wake up” upon detection of a button
press or LF signal from the control module. The fob will return to “sleep”
mode once the event that woke it up is completed.
When a fob is in close proximity, 2-3 inches, from other vehicle control
units, cell phones or inductive cell phone charger pads, electrical
signals from these devices can prevent the fob from returning to “sleep”
mode and can reduce battery life. Additionally, when in close proximity
to these other electrical devices, their emitted electrical signals can
saturate the fobs internal receiving antennas and prevent the fob from
receiving proper LF signals.
It is recommended for optimal Fob performance and battery life that a
distance of at least 5-6 inches minimum be maintained between fobs
and other such mentioned electronic devices.
Due to the chemical process inherent in batteries, the performance of
the e-ASK fob will be degraded at extreme temperatures. Operating
temperature ranges will vary across batteries from different
manufactures. For commercially available CR2032 batteries the typical
operating temperatures ranges from –0C to +60C.
At cold temperature, the batteries chemical process is slowed down and
can result in reduce Fob range performance or an inoperative fob.
When the battery is returned to warmer temperatures, normal
performance will return. Extreme cold temperatures, below –20C, can
cause a battery to freeze and fail due to expansion of internal plastic
components. Simply replacing the battery will allow the fob to function
normally.
At extreme hot temperatures, the batteries chemical process is
accelerated. This will result in a reduced life expectance of the battery.
Normal fob range performance can be expected at higher temperatures
as long as manufacture limits are not exceeded.
