7. GENERAL INFORMATION
7.1 DIAGNOSIS
7.1.1 DIAGNOSIS NOTE
1. NOTE
This product is an amplifier product without volume control.
Therefore, if an audio signal from CD player, etc is inputted to the Transmitter, a loud sound will come out from receiver.
The signal generator or some products with Pri-out is recommended.
2. NOTES ON REPLACE OF PARTS
(ID-related)
The ID number for an individual product is stored in the RF module. (TX module : AXF7015 and RX module : AXF7016)
It should be noted that wireless communications cannot be performed unless these ID numbers are identical.
Replacement of the TX or RX module
Upon replacement of the TX (AXF7015) or RX (AXF7016) module, ID learning setting is required.
Method of ID learning setting
ID learning is an act which sends the ID number of a transmitter to a receiver and makes ID of a receiver the same as a transmitter.
i) Press ID learning button (RX ASSY : S8902) and hold it.
ii) D8901 on RX Assy will blink. Receiver is ready for learning ID.
iii) Press the "Channel" button of Transmitter and hold it over 3sec.
iv) Transmitter's Channel LED will blink. It will trigger the ID learning process
v) If Receiver finishes learning, D8901 will change to lighting from blinking.
Note : The ID learning process won't be enabled if only press the button for either Transmitter or Receiver one side.
It must press two sides in the same time.
*
Do not use the "ID learning setting" to customer's receiver unit when there is no customer's transmitter unit.
Using "ID learning setting" in this case, ID data of the customer's receiver unit will be changed to the another ID that is
same as a substitute transmitter unit.
When using "ID learning setting" to customer's receiver unit without customer's transmitter unit, ask customer to bring the
transmitter unit and set the ID number for each pair of the customer's transmitter and receiver unit.
3. If receiving condition is unstable.
Check if there is a source of interference with signal reception, such as a wireless LAN, Bluetooth device, microwave, or digital cordless
phone, near the products. If only a specific channel can be received, or if reception is unstable only on a specific channel, existence of
source of interference near the products is likely the cause.
If it is confirmed that unstable reception is not caused by some source of interference, the Tx or Rx module may be defective.
If so, replace the module.
