Timeguard FBT4 2 Hour Electronic Boost Timer and Fused Spur

The required boost time is selected by pressing the button marked boost, repeatedly. The LEDs adjacent to the time markers will light up in sequence, showing the selected boost period.

• The boost sequence is as follows;

First push gives ¼ hour boost (LED opposite ¼ is ON)

Second push gives ½ hour boost (LED opposite ½ is ON)

Third push gives 1 hour boost (LED opposite 1 is ON)

Fourth push gives 2 hour boost (LED opposite 2 is ON)

Fifth push returns to zero boost (all LEDs are OFF)

• Once the boost selected is underway, the LEDs will go out

sequentially, indicating the approximate boost time remaining.

Example: 2 hour boost has been set, all LEDs are on;

After 1 hour and 58 minutes, the 4 hours LED will flash for two

minutes, and then will go out indicating 2 hours are remaining.

After 58 minutes the 2 hour LED will flash for two minutes,

and then go out indicating 1 hour remaining.

After a further 28 minutes, the 1 hour LED will flash for two minutes,

and then go out indicating ½ hour remaining. After a further

13 minutes, the ½ hour LED will flash for two minutes, and then

go out indicating 15 minutes remaining.

After a further 13 minutes the ¼ hour LED will flash for two minutes,

and then go out, indicating that the boost period has finished.

• In this way the user has an approximate guide to the remaining

duration of the boost.

• If the boost button is pushed and held down, the LEDs will cycle

upwards with 1 second between each change, in sequence
