If the board ground is referenced to DC return, you could discharge it from the negative side of the batteries, if accessible.

Hi Charles, I thought you were Mr. RF these days and didn't stoop to lowly EMC tests ;-) Agree with Charlie on EN 55035 - - > IEC 61000-4-2 @ 8kV air and 4kV contact. Removing the built up charge from the insulated surface will be the challenge during testing. All the best James ---- Charlie Blackham wrote ---- Charles Assuming it’s infrared only, EN 55035<tel:55035> would be a suitable product standard (Infrared remote controls are referenced as ancillary/support equipment for TVs in the informative Annex J) A wireless remote would additionally be tested to EN 301 489<tel:301%20489>-x, but the test levels are the same Best regards Charlie Charlie Blackham Sulis Consultants Ltd Tel: +44 (0)7946 624317<tel:+44%20(0)7946%20624317> Web: https://sulisconsultants.com/<https://urldefense.com/v3/__https:/sulisconsultants.com/__;!!LVMHySo!nqPjS6U_onUumPWYl9vbyPEztNfet_jjsgMIQK91T71AyTtB110A4RYIMIP1XLgCqEeMljSoH659y1lXH-_uFW94SPU$> Registered in England and Wales, number 05466247<tel:05466247> From: Chas Grasso <charles.gra...@dish.com<mailto:charles.gra...@dish.com>> Sent: Thursday, April 27, 2023 11:24 PM To: EMC-PSTC@LISTSERV.IEEE.ORG<mailto:EMC-PSTC@LISTSERV.IEEE.ORG> Subject: [PSES] ESD standards for testing remotes Hello gurus!
