Preparation for Tuning Antennas
Antenna tuning requires use of field strength sensor Q13626-01 supplied with
ASC tool kit.
1 For units without G-Site put unit in Stand Alone mode by disconnecting J4 on
the DCB board and placing jumper on light microreader board at JP3.
Note: JP3 and J4 can never both be in or both out. One and only one must always
be in, the other out.
2 If applicable, restore CRIND tray to operating position.
3 Restore power to unit(s) and cold start the CRIND. Refer to MDE-2562, CRIND
Service Manual for detailed instructions.
Note: Be sure transmitter cables are connected before restoring power.

jump jack.
