Vertex Standard VX-241 Servicing GuideThis article serves as a guide to what you will need in order to perform a full service and alignment on the Vertex Standard EVX-531, Vertex Standard EVX-534Vertex Standard EVX-539.

Vertex Standard EVX-534 & EVX-539 Gotcha

There’s a very but significant gotcha with the programming & aligment software on the EVX-530 series which applies to the EVX-534 and EVX-539. 1/2 way through the life of the Vertex Standard EVX-534 and EVX-539, these two radios had a feature-lift where Vertex Standard changed the display from a LED 14-segment display to an LCD dot-matrix display. For the old 14-segment display you’ll need the CE-142 programming software but for the LCD-enhanced display models, you’ll need the CE-151 programming software. This does not apply to the EVX-531. The EVX-531 requires the CE-142 programming software only as there’s ever been one version of the no-keypad EVX-531 model.

Below are all the parts needed to refurbish a Vertex Standard EVX-531 digital two-way radio. Whilst there are technically two models (G6 & G7), for the purposes of refurbishment, they both take the same housing etc. However, it’s worth checking the service manual regarding the iteration as there have been subtle changes in the EVX-531 over its lifetime.
