TRANSMIT TER USAGE & CARE
PRECAUTIONS
Your two 3-button transmitters are fairly durable devices that can endure
common jolts or falls from a pocket. (Be aware that falls on hard surfaces
may nick the plastic or the painted surface.) Your transmitters can even
be submerged in water to 1.8 meters (5.9ft.) However, your transmitters
can still be damaged by excessive heat, direct sunlight for extended peri-
ods, rapid movement through water (we advise against diving/surfing with
your transmitter) . If water gets inside, remove batteries and allow to dry
thoroughly before testing.
Never keep both transmitters on the same keychain. Always keep one
transmitter in a safe place at home or work, so if you lose the one on your
keychain you will have a spare available.
CHANGING THE BATTERIES
There are two CR2032 Lithium button-cell batteries inside your transmit-
ters, which last about 1 year with normal every-day use. When the battery
is getting low, the range will become shorter and the LED will become dim
or not light at all. Snap open the case at the keychain hole to open. Be
careful when snapping open the case with a screw-driver, so you don’t dent
the plastic.
COMMUNICATION RANGE
Your transmitter’s range is adversely affected by RF noise. However, the
typical in-city range is often greater than 20m (>65ft), and normal range in
the country side (or any low RF noise area) can be as high as 50m (165ft.).
Please keep in mind, however, that if metal objects (coins in your pocket)
come in contact with the transmitter, range may be adversely affected.
Also, your proximity to high-power TV station antennas and or powerful
mobile phones will also limit range.
