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-420R by two 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.
