ApexPro Transmitter

 c – View the Label. This is a combination of the TTX number and an

abbreviation of the transmitter model. The label automatically

changes as you change the TTX Number. For example, an ApexPro

transmitter set at TTX number 7700 would be labeled “7700AP”.

 d – View Other Transmitters at This Frequency. If there are any

other transmitters set to this frequency, there could be interference

with signals from this transmitter. Avoid this whenever possible.

 e – Check the Clear Failures With This New Setting box. This resets

any failed status that was indicated in the Power-up Self-Test Status

section of the Program ApexPro Transmitter window. When this

option is checked, failures will be cleared when you select the OK

button.

 f – View Incompatible Transmitters. Incompatible transmitters have

frequencies within +/

– 12.5 KHz. These transmitters cannot be

admitted on the same system. If a list of any other transmitters

appears in this box, the TTX number selected cannot be used and the

OK button is disabled. You must select a different TTX Number.

 g – Channel and Zone (JAPAN ONLY) are coordinated with TTX

Number in that they change as you change the TTX Number. Refer to

Reference Lead Setting

For 5- or 6-Lead Cables

The reference lead setting has no effect when 5- or 6-lead cables are used.

For 5- or 6-lead cables, the reference lead defaults to RL.

For 3-Lead Cables

For 3-lead cables, one of the lead wires (LL, LA, or RA) is used to connect the

reference voltage to the patient. Selection of the reference lead determines

which ECG waveform will be displayed at the CIC, according to the table

below.
