Narrative:
Called to placard captain radio altimeter. During the process of issuing placard I inadvertently did not issue placard of TCASII inoperative as required in MEL xzx. A MEL placard was not issued due to confusion at the time of issue. Captain radio altimeter MEL reference zxy requires issuance of placard and lmp (lower minimum performance, CAT ii). I inadvertently overlooked issuance even though I had it written on my note pad. Aircraft was repaired oct/thu/00, and placards cleared.

Narrative: CALLED TO PLACARD CAPT RADIO ALTIMETER. DURING THE PROCESS OF ISSUING PLACARD I INADVERTENTLY DID NOT ISSUE PLACARD OF TCASII INOP AS REQUIRED IN MEL XZX. A MEL PLACARD WAS NOT ISSUED DUE TO CONFUSION AT THE TIME OF ISSUE. CAPT RADIO ALTIMETER MEL REF ZXY REQUIRES ISSUANCE OF PLACARD AND LMP (LOWER MINIMUM PERFORMANCE, CAT II). I INADVERTENTLY OVERLOOKED ISSUANCE EVEN THOUGH I HAD IT WRITTEN ON MY NOTE PAD. ACFT WAS REPAIRED OCT/THU/00, AND PLACARDS CLRED.
