Wall Power
The ON/OFF key powers up the TriCoder once the 5-volt power adapter is
plugged in. If accessing wall power with the power adapter, it is critical
that you use ONLY the 5-volt power adapter that comes with the TriCoder.
DO NOT plug in any other power adapter you may have even if the voltage
matches – other specifications may not. Plugging in an adapter other that
the correct one can cause SEVERE damage to your TriCoder costing
hundreds of dollars to repair or replace.
Battery Power
For portable use, there are two levels of batteries used by the TriCoder.
Three AA batteries provide the main power for the scanner, display and
electrical circuitry. Either alkaline (including Alkaline rechargeables),
Nickel Metal Hydride rechargeable batteries or NiCad rechargeables may
be used. Nickel Metal Hydride (NiMH) is preferred over NiCad. Alkaline
batteries (including Alkaline rechargeables) should provide approximately
20 hours of continuous scanning (without accessing voice messages), as
well as retain the data in memory and provide for real-time clock operation
for several months before tapping the backup battery source. NiMH or
NiCad rechargeable batteries will give approximately 40% less operational
time than alkalines.
If you are using rechargeable batteries, there is recharging circuitry built in
to the TriCoder. To use the recharging circuitry, you must change a jumper
inside the TriCoder itself and then plug in our 5v Power Adapter. For best
results, use only NiMH rechargeable batteries.
By default, the TriCoder is set up to use regular alkaline batteries with the
recharging circuitry OFF. Recharging alkaline batteries may cause the
batteries to explode and leak battery acid throughout the TriCoder. With
JP3 jumper installed, only use rechargeable batteries. The jumper inside the
TriCoder is located above left of the POWER jack and is labeled JP3. The
jumper must cover BOTH pins in order for the recharging to work. See
Appendix F: Jumpers, Switches, and Adjustments for an internal
diagram of the TriCoder. Recharging takes approximately 8 hours for a full
charge if batteries are fully discharged first.
If you are using alkaline batteries (either regular or rechargeables) and
have selected the NiCad/Rechargeables setting in the Speaker/Battery
setup parameter (See Chapter 6; TriCoder Setup), the TriCoder generates
the following error message:
The TriCoder can detect the battery type (when batteries are new) and
compare it to the Speaker/Battery setting. If it detects Alkalines when
NiCads are specified, you should NOT use the recharging feature. Make
