Troubleshooting
Problem
Possible cause and solution
It will intermittently play the Leaving Message of
Mailbox.
Noise interference exists. If this cannot be fixed, set “non-silent compression
SYS_4_0_[2]” to improve the situation; but the voice capacity will decrease by 20%.
EVM does not pick up calls.
If the POW lamp is not flashing, please check the power supply.
Please check the wiring and make sure the incoming ringing is correct.
PABX locked the extension port. Please set the Port Auto-detection. SYS_4_7_[2]
EVM responds after External line 2 ~ 3 rings.
This is normal. Set the “ring times SYS_3_1_[0]” for improvement.
Immediate conversation over the phone is
inaccessible after the called responds to the call.
This is normal while the EVM is waiting. Use the Pickup Code or ID Code to allow calls to
go through Un-supervise Transfer.
EVM has not finished Auto-configuration yet. Please dial three times for "a busy extension"
and "an available extension (do not answer)".
EVM always announces that the number dialed is
faulty when in fact the line is busy, and vice versa.
Please exchange the parameters for Error tone with the Busy tone.
EVM announcement repeats: "Hold on, please"
every 4 seconds, and the call is not on hold.
Hook-Flash time is too short. SYS_7_1_[ ]
Occasional occurrence – insufficient DTMF Receiver for PABX.

EVM announcement repeats: "Hold on, please"
every 4 seconds, and the call is being held.
PABX Dial Tone frequency is outside the detection range (300 ~ 640 Hz), please set not to
detect the frequency. SYS_4_8_[2]
Occasional occurrence – insufficient DTMF Receiver for PABX.
※
After "Hold on, please" has been announced, the
call is disconnected.
The Hook-Flash time set under EVM is too long. Where the Hook-Flash time is less than
0.13 seconds, EVM does not Auto-configuration, it must be entered manually.

Extension number is correct, but EVM announces
"Wrong number" or "Line busy".
Dialing way is incorrect. SYS_5_1_[ ]
Function code for call transfers is incorrect. SYS_6_1_[ ]
PABX requires longer DTMF. Please set SYS_5_1_[2]
Occasional occurrence – insufficient DTMF Receiver for PABX.
※
EVM fails to announce that the called line is busy
or is no answering.
If the CPT is delayed or reminder tone exists before the CPT, please set to delay the
detection of CPT. SYS_7_3_[ ]
If the frequency of CPT is outside the detection range (300 ~ 640Hz), please select not to
detect the CPT frequency. SYS_4_8_[2]
CPT is irregular, please set larger tolerance for CPT detection. SYS_4_6_[1]
CPT is too weak, please set the detection sensitivity of internal CPT. ADM_5_9908_x[ ]xx
Key Telephone system has been set to Voice Call, please change it to ringing.
Function code is required to retrieve the external line, or the procedure of retrieval is
incorrect. SYS_6_2_[ ], SYS_5_5_[ ], SYS_5_6_[ ]
Hook-Flash time is either too short or too long. SYS_7_1_[ ]
Others
Use the hand-free of the PROG-TEL, press # to exit program setting and return to the Greeting.
When the EVM finished playing the message and silence resumes, the procedure of the Line-1
transfer can be monitored through the speaker of the PROG-TEL to pin-point the problem.
※
DTMF Receiver in PABX is inadequate. The suggested solution is as follow:
1.
Increase the installation of DTMF Receiver for PABX.
2.
To set program for EVM to Dial Pulse (DP) Transmission.
3.
Disperse the Extension Line of EVM in several Interface Cards of PABX. (For example, every SLT Card of KX-TD contains only two-circuit
DTMF Receiver.)
