ADSL mode
When MT-8002 is switched to ADSL mode, it can determine if the net service is
either 10MB or 100MB Ethernet.
• To test an Ethernet line, just plug the RJ-45 into the RJ-45 jack near the button
of MT-8002.
• To test a Ethernet port, use a standard RJ-45 cord plug the 2 ends of the cord
to the RJ-45 jack of MT-8002 and the Ethernet port.
• If the LED is always on, the LAN speed is 10 MB, if the LED is flashed, the
LAN speed is 100MB, otherwise the LAN has no signal.
Cable Mode
MT-8002 provides a Cable continuity test function.
• Turn the switch to CABLE position.
• Connect the two end of tested cable to the alligator clip.
• If the tested cable is continuous (good) the CABLE LED will on.
• If the resistance of the tested cable is < 300Ω, the CABLE will be light but the
brightness depends on the impedance. The lower resistance will make the
LED more bright.
• Otherwise, the tested cable is open or the resistance of the test cable is >
300Ω.
CAUTION:
When testing circuits which are close to a battery source, the pops in the
handset receiver that result from clipping onto a line may be quite loud.
Although there is protection against acoustic shock built into the test set, if
the receiver is held tightly against the ear, acoustical shock may occur.
MAINTENANCE
WARNING:
_ To avoid electric shock, do not perform any servicing other than that
contained in the operating instructions unless you are qualified to do so.
_ Disconnect clips from any metallic connections before performing any
maintenance.
If moisture should get inside the test set, let the test set dry at normal room tem-
perature for 24 hours.
DO NOT HEAT THE TEST SET.
Moisture can provide a leakage path that may conduct hazardous voltages to
you. DO NOT USE the test set if wet.
Keypad Care
Daily use of your test set results in various liquids, dirt, and other foreign material
building up in your keypad. The keypad may be cleaned by using a soft tooth-
brush with soap and a little wet cloth.
Do not use a petroleum-based or chlorinated cleaning agent as it will harm the
keypad. Let the test set dry before using!
