EMT757 PROGRAMMABLE DIGITAL TIME SWITCH

EASY USER GUIDE

At last, here's the instruction manual they left out of the box! This is an easy-to-read and

comprehensive guide that explains how to use the popular EMT757 time switch.

The EMT757 time switch has been sold for many years, previously in the UK by B&Q under the

Everflourish brand, and currently under the ExtraStar brand found on Amazon. Clas Ohlson also sells

it under their Cotech label.

It's a versatile 7-day time switch that with 20 individual on-off programmes, a countdown timer that

switches on/off after an elapsed period, and a random burglar-deterrent function. A built-in battery

backup maintains the timer settings when the timer isn't in use (for months if not years), or when

there's a power cut. This means you can also set the timer in your hands, without struggling to set it

up in situ, plugged into a mains socket.

I've used them for many years and have got to know them very well. The problem for many users is

that the digital display and buttons are pretty small, and the supplied generic instructions take a bit

of digesting (and contain one or two errors), hence I've written this guide to make life easy for those

who might be struggling with this popular timer.

Users are warned against controlling electric heaters, irons, cooker rings etc to avoid fire risk (eg

with unattended appliances being accidentally left on, something falling in front of them in the

meantime or being forgotten about).

Page 5 ABOUT THE BATTERY The EMT757 has a built-in rechargeable NiMh cell that powers the digital clock (but not the relay), even if the timer isn’t plugged in. This also keeps the clock going even if there’s a power cut. The battery recharges fully within 2 hours and lasts for many months (or longer) between charges.
