The ESL is in sleep mode almost the entire time. The device wakes up at regular intervals
(called the poll time) and it then transmits a poll request to the base station. When the base
station has no data to send, it just acknowledges the poll after which the ESL immediately goes
back to sleep. The poll rate is configurable and is set to 20 seconds by default. A higher poll
rate will decrease the power consumption but will increase the response time.

The power is supplied to the EE-750R by four replaceable Alkaline AAA size batteries (not
included). The typical operation time on a set of batteries is 5 years when using quality alkaline
batteries, based on a poll rate of 20 and on average two display updates per day.
