Display Functions
Asleep / Awake Mode
Asleep is a battery-saving mode in which the display 
goes blank after a five-minute period of no button or trig-
ger switch activity. An RF test lasting longer than five 
minutes will stop and the LCD display backlight will go 
out as the Signal Tester enters the sleep mode.
The display comes Awake from sleep mode when any 
display button is pressed. RF testing will not automati-
cally restart. To resume testing press the trigger switch.
Battery Life Indicator
On the right side of the display is a series of four bars 
located under the word BATT. See F
IG
. 2. The presence 
of all four bars indicates a fully charged battery. The 
bars decline in number as the Signal Tester is used and 
the battery discharges. All Matrix signal tester batteries 
should be re-charged using a Graco Matrix battery char-
ger at the end of the working day to assure good perfor-
mance the next day.
Batteries can be recharged at anytime without 
battery damage.
At one bar on the display you will have about 
20-40% of the charge remaining.
If an RF Signal Tester is removed from service 
for an extended time the battery should be 
removed and recharged.
If you see the message “Remove Low Battery - 
Wait 30 Seconds Then Replace”, follow the 
instructions and replace the low battery with a 
fully charged battery. Do not do this proce-
dure during RF signal testing.
Even when a Signal Tester is idle (asleep), the 
Signal Tester is still functioning and the battery 
will be used.
