Firstly press the button and pull the key upwards. Insert a screwdriver in the key slot and turn it slightly. The fob lid locks will open. Remove the old cell and insert a new CR2032 cell. Here I am using a cheaper one used for PC CMOS cell, which costs me Rs 10 INR. After replacing the cell just put the lid back and press. The new cell is working good, will tell the performance/ life after long term use.

JDSU   SmartClass Ethernet Tester Single RJ-45 port for electrical testing, Single SFP port for optical testing. Menu screens provide a series of selections that take you to another menu screen, a data entry screen, or a results screen. Here we are going to perform L2 Traffic test. Now we will select Optical Ethernet. We are using 1550nm 1.25G SFP. Then start the test. Here Tx Acterna Frames are count of Acterna test frames transmitted since starting the test and Rx Acterna Frames are count of Acterna test frames received since starting the test. Both our Tx and Rx Acterna test frames counts are same means the loopback is without error.
