The original M2A has been replaced with the M2A-XL Stand Alone Transmitter. The M2A-XL has an alternate housing, which is slightly taller, wider and deeper, but the electronics and operation are the same as the original M2A housing. Since this housing is deeper than the original M2A, longer standoffs are required inside to properly bring the display up to the transmitter’s window.
Changes related to using the new, alternate housing are outlined below:
- M2A-XL is the new model name for the original M2As installed in the larger housing. The new model name is visible on the label around the display.
- The Manual is different. The dimensional drawings have been revised to reflect the larger enclosure.
- New part numbers are utilized for the M2A-XL. The letters “XL” are replacing the “RK” within the former M2A part #’s.
- Inside the M2A-XL the electronics and operation are exactly the same as the original M2A.
The only difference is the larger enclosure. - The original M2A has been discontinued. As a result, the original M2A sections of the current price book were removed and replaced with the M2A-XL price list sections.
