How to Read the Serial Number on Leitner Wireless

The serial number can be located underneath the headset base. For swivel mics it can also be located behind the plastic ring on the microphone side (if it is dual-ear)

Note: We will not be required to find the serial number for LH280/380 mics. Just use the serial number from the charging base.

We only need to get the serial numbers from the mic when we are replacing that piece. If you are replacing just the base, or the base and microphone, you only need the base serial number

A serial number will look like this on older units ---> S/N 20054655007

For newer units the format is the same, but the SN can be found underneath the bar code.

The first 2 number “20” mean the year, in this case 2020

The last 2 digits “07” mean the month of the year, in this case July

The remaining 6 digits “054655” are just the rest of the serial number.

To view the serial # on the swivel mic we need to detach the plastic ring. We DO NOT need to remove the cushion from the ring.

Note: You may also see Letters in the serial number. This indicates that your unit has an updated software version.

For all other headsets (Leitner corded, OfficeRunner, DeskMate, and Marathon) we want to make sure we’re doing the right job asking questions of our Customers to make the best warranty replacement decisions:

• Are you the person who bought the headset?
• When did you order the headset?
• About how long have you had the headset?

We want to avoid questions like:

• I see you have a few headsets on your account, is this one of the newer ones?
• There are some headsets still under warranty, and some that aren’t – is this one of the newer headsets?
