Since the transmitter requires very little power, batteries
will keep much longer. We recommend the use of high-
quality alkaline batteries.
Rechargeable batteries:
Operation of the transmitter with rechargeable batteries
is not recommended because of the lower cell voltage
(battery = 1.5 V, rechargeable battery = 1.2 V) and the self-
discharge of rechargeable batteries. Quick feedback of the
transmitter on low charge status of the transmitter power
supply would result.
