Battery Replacement - Ideal 33-856 Instrucciones De Operación

The Pass icon will also be on with a flashing Uplink icon if a network cable has the 1-2 and the 3-6 pairs trans-
posed to indicate a properly wired uplink (crossover) cable. In Voice mode, the Rev icon will flash if all connected
pins are in reverse order and the Pass icon will also be on if all 6 connections are present. Telephone modular plug
cables used between the wall jack and a phone set are usually reverse pinned.
Definition of Errors – The three classes of faults discussed below are in order of severity. The severity has to do
with the ability of a more severe error to mask less severe errors. For example, if there is a short in the cable, mis-
wires and split pairs may not be detected for the pairs involved in the short fault.
Short – The pair has a low resistance connection from one wire of the pair to the other wire of the pair or to any
other wire in the cable or the shield. A short is indicated by the Short icon being on and flashing -'s in the appro-
priate pin positions on the second line for the pin numbers involved in the shorts plus a flashing S icon if the
shield is shorted to a pin.
Miswire – A wire or both wires of a pair are not connected to the correct pins at the other end of the cable.
The wire map shows the pin numbers line 1 (main) line 2 (remote). A reverse pair is a special case of a miswire
in which the pair is wired to the correct pair of pins or to another designated pair of pins, but the two leads are
reversed. The VDV MultiMedia Cable Tester is able to test for split pair errors as long as the wiring errors are in
pairs. The Fail icon and the pin numbers, which are miswired, will be flashing.
Split Pair – A split pair is an error in the twisting of the wires together within the cable. The cables generally are
made up of eight wires twisted together in 4 pairs. These 4 pairs are designated as pairs by the wiring standards and
are intended to carry a signal and its return. 1 & 2, 3 & 6, 4 & 5 and 7& 8 are the pairs designated by T568A/B for a
RJ45 jack or plug. A cable can be wired with correct continuity but not with correct pairing. This most often happens
when the cable is terminated consistently at both ends, but in the wrong order. A dynamic or AC test is required
to detect this type of error. If the only error is a split pair error, the cable has correct continuity. If cross talk is not
a concern, as in flat satin cable, the cable is good if the only error is the split pair error. The Split icon and the pin
numbers on the first and second line of the wire map with split pairs flash when there is a split pair error.
VDV MultiMedia Cable Tester has the ability to turn off the split pair error testing. Pressing the button for the cur-
rent cable test mode for more than 2 seconds turns off the split pair testing. The "Split" icon and the word "OFF"
appears on the screen momentarily to indicate this. The split pair testing will resume the next time the tester is turned
on, or may be toggled back on by another 2 second press of the current test mode button.

BATTERY REPLACEMENT

When the battery low icon is on, the battery should be replaced as soon as practical. The cable testing results will
become unreliable when the battery reaches about 4.5 volts. To replace battery:
1. Remove the screw from the battery door on the back of the unit with a #1 Phillips-head screwdriver.
2. Pull battery out of cavity and remove battery snap.
3. Connect a new Alkaline 9 volt battery to battery snaps. Place battery back into body with battery snaps placed
toward front end of compartment.
4. Replace battery door and screw being careful to not over tighten the screw.
