Appendix D. Self test and battery replacement
Testing the Main Unit: The "10/100/1000 LAN Test" section of
the Main Unit is equipped with a self-test feature that is automati-
cally activated when the unit is powered ON. Self-test progress is
indicated by a series of sequentially flashing LEDs. If the TVR1000
passes the test, all LEDs will be left OFF, except the power ON LED.
If the unit continues to self-test or the red power LED is dim, it is
time to replace the 9V battery.
The Main Unit's "Cable Tests" section's LEDs are tested by connect-
ing a Straight thru patch cable (included) between the Main Unit's
"Cable Tests" jack and the Remote Probe's "Cable Tests" jack. The 4
LEDs on both units should light in "Straight" order.
If you suspect a problem with the Main Unit, replace the battery
(weak tone generator, dim LEDs, etc.). The battery compartment
is located in the lower-back of the Main Unit. Remove the snap-fit
cover. Use a 9V alkaline battery (NEDA type 1604A).
Testing the Remote Probe: To test the Remote Probe's tone detec-
tion capability, hold the probe's tip next to the Main Unit's "Cable
Tests" jack and depress the "Trace" button. A tone should be heard
(having a short patch cable connected to the Main Unit's jack will
amplify the tone). If weak, replace the battery.
To test the Probe's "Cable Tests" jack, perform the same test as
described for the Main Unit (above).
To replace the battery, remove the two screws holding the probe's
battery cover in place. The battery cover is located on the lower
back of the probe. Use a 9V alkaline battery (NEDA type 1604A).
When replacing the cover, do not overtighten.
