7.5 Replacing the Backlight (Sold Sepa rately) (Applies
Only to GT30)
About the backlight
The average service life of the GT30 backlight is 50,000 hours (at room temperature, normal humidity,
and 24 V DC). (“Service life” refers to the period over which the brightness diminishes by half, and does
not mean that the backlight no longer lights at all.) If the backlight has become dim, it should be replaced
with a replacement backlight (sold separately).

Replacing the backlight
When replacing the backlight, always turn off the power supply to the GT30, and then refer to the
procedure outlined below.
1. Take off the cover and disconnect the connector.
Remove the cover, and pull out the connector in
the upward direction, as shown in the illustration.
2. Pull out the backlight.
Gently pull out the backlight.
To install the new backlight, reverse the procedure.
*After replacing the backlight, be careful that the
backlight cable is not pinched by the case, cutting
through it.

When replacing the backlight, always turn off the power supply to the main unit. Also, we recommend
wearing gloves when doing this, to prevent injuries.
