NEC MH150/MH160 Mobile Handset Administration Guide - Revision 2
Code Mismatch!
The software loaded into the handset is incorrect
for this model handset.
Verify the License Management value is correct.
Replace the software image on the TFTP server
with software that is correct for the handset
model.
DCA Timeout
The handset has detected a fault for which it
cannot recover, possibly due to a failure to
acquire any network.
Turn the handset off, then on again. If error
persists, contact NEC Unified Solutions Technical
Support and report the error.
DHCP Error (1-5)
DHCP Error 1.
DHCP Error 2.
DHCP Error 3.
DHCP Error 4.
DHCP Error 5.
The handset cannot locate a DHCP server. It will
try every four seconds until a server is located.
The handset has not received a response from
the server for a request to an IP address. It will
retry until a server is found.
The server refuses to lease the handset an IP
address. It will keep trying.
The server offered the handset a lease that is too
short. The minimum lease time is 10 minutes but
NEC Unified Solutions Engineers recommend at
least one-hour minimum lease time. The handset
will stop trying. Reconfigure the server and power
cycle the handset.
Failure during WEP Key rotation process
(proprietary feature).
DHCP Lease Exp
yyy.yyy.yyy.yyy
y…y = DHCP server IP address.
DHCP is not responding to renewal attempts (at
least one renewal succeeded).
The handset failed to renew its DHCP lease,
either because the DHCP server is not running, or
because the configuration has been changed by
the administrator. The handset will attempt to
negotiate a new lease, which will either work, or it
will change to one of the above DHCP errors (1
through 4).
DHCP NACK error
yyy.yyy.yyy.yyy
y…y = DHCP server IP address.
DHCP server explicitly refused renewal
The DHCP lease currently in use by the handset
is no longer valid, which forces the handset to
restart. This problem should resolve itself on the
restart. If it does not, the problem is in the DHCP
server.
DL Not On Sector
Handset software download files are incorrect or
corrupted.
Download new software from the NEC Unified
Solutions website per Software Maintenance.
DO NOT POWER OFF
The handset is in a critical section of the software
update.
None. Do not remove the Battery Pack or attempt
to power off the phone while this is displayed.
Doing so may require the handset inoperable.
Duplicate IP
The handset has detected another device with its
same IP address.
If using DHCP, check that the DHCP server is
properly configured to avoid duplicate addresses.
If using Static IP, check that the handset was
assigned a unique address.
Erase Failed
Download process failed to erase the memory in
the handset.
Operation will retry but may eventually report the
error “int. error: 0F” Power cycle the handset.
Erasing Memory
Handset has determined that a download should
occur and is erasing the current software from
memory.
None. When the progress bar fills the display line
the erase operation is complete.
Do not turn the handset off during this operation
Files Too Big
Handset software download files are incorrect or
corrupted.

Solutions website per Software Maintenance.
