Should you ever need to open a module and handle the circuit board, use the wrist strap to
connect your wrist to a suitable ground first. Electrostatic discharge can destroy or severely
damage the integrated circuits in the power supply, processor, and modules.

On-Site Programming Maintenance

You can perform onsite maintenance with a 4424LD+ or MLX-20L console or a PC running
WinSPM software. Onsite programming maintenance is preferred over remote programming
maintenance, if feasible, because remote programming overrides onsite programming, except
when onsite backup or restore is in progress.
If programming maintenance is being done by a local PC, both the 4424LD+ telephone and the
MLX-20L telephone can continue normal call processing and station programming operations.
However, if you attempt to access maintenance tasks with a 4424LD+ or a MLX-20L telephone
while a local PC is performing the same maintenance operations, you are denied access to the
task and notified with a beep.

Setting Up the 4424LD+ Programming Console

To be used for system programming a 4424LD+ telephone must be connected to the first jack on
the leftmost (Slot 1) 024 TDL or 412 LS-ID-TDL module. For complete installation instructions,
refer to "Connecting Telephones to 412 LS-ID-TDL and 024-TDL Modules" in Installation.
4424LD+ Failure
If the 4424LD+ console does not work, follow the steps below.
1. Replace the 4424LD+ console with one that is known to be working (if available).
2. If the failure persists, or if a working 4424LD+ console is not available, connect the original
4424LD+ console directly into the appropriate TDL jack on the control unit using a cord that is
known to be working.
3. If the trouble clears, replace the original cord.
