4.5 Activating a CDMA LMU-4530™
Check with the CalAmp Sales team for availability of the LMU-4530™ with CDMA modems.
For CDMA
devices, the activation sequence you will use varies from carrier to carrier. Each of the supported carriers is
documented below.
To obtain an account, a CDMA carrier will generally ask for three things, the Manufacturer, the Product
Type and the ESN. Obviously the first two items are answered by “CalAmp LMU”. The last one is a
little misleading. The ESN on the LMU is the CalAmp serial number. The one the operator is interested
in is the MSN-D (which they call the decimal ESN). DO NOT give them the CalAmp ESN (i.e. the top
one on the label). It will only lead to the carrier telling you that the product doesn’t exist and they can’t
activate it for you.
What you should get back will vary from operator to operator; however at very least it will be the MDN
(Mobile Directory Number) and MIN (Mobile Information Number). You should also ask for the SPC
(Service Programming Code) in case it is not 000000. The SPC is effectively a password to the
modem which allows you to program some of the more sensitive items (ex: the MDN and MIN). Please
note that the MIN and MSID can be the same value.
4.5.1 Activating a CDMA LMU-4530™ – Verizon
Verizon supports a system that allows CDMA devices to be provisioned Over-The-Air. A CalAmp LMU-
4530™ will automatically use this system to attempt to self provision. This procedure assumes that the
LMU-4530™ has never been provisioned or activated before.
1. Power on the LMU-4530™, making sure you can observe the behavior of the Comm LED.
2. Wait until the Comm LED turns solid. This could take up to 5 minutes.
3. If after 5 minutes you observe that the Comm LED transitions from a slow blink to a fast blink
several times (i.e. more than twice) you will need to contact Verizon Wireless for further support on
account activation.
Once configured, you may verify that the LMU-4530™’s modem has registered to the CDMA network.
