FCC ID: OHGMNP-310 To Whom It May Concern: We asked the test laboratory to confirm that the handset & the base were modulated when they were tested, and they confirmed this. Also the original schematics were not acceptable and they resent new schematics. The original did not include an operational description. Sincerely, Sid Sanders
