Power Requirements
To conserve power, the FLEX protocol for two-way paging provides low power modes
of operation. In receive mode, all logic and receive circuits are powered while waiting
to receive a message. In standby mode, all circuits are in a low power state for power
economy. In transmit mode, all logic circuits and the power amplifier are active and
consume large amounts of current for short durations.
a. Does not include current due to RS-232 communications.
b. No Valid RS-232 voltages and all 8 I/O lines configured as inputs.
