Opinion

BRYNER, Chief Judge.

Following a jury trial, Edward Thayer was convicted of driving while intoxicated (DWI). AMC 9.28.020. Thayer appeals, challenging the admission of the breathalyzer test results at trial and the trial court’s refusal to admit a transcript of expert witness testimony from a pretrial evidentiary hearing. We affirm.

On October 23, 1982, Thayer was arrested for DWI. A sample of Thayer’s breath was tested on Smith & Wesson Breathalyzer model 900A, serial number 93208. The test results showed a blood-alcohol level of .21. In November of 1982, Thayer’s attorney received information that Smith & Wesson, the manufacturer of breathalyzer instruments, had issued a customer advisory warning of the possibility that some breathalyzer instruments might be affected by radio frequency interference (RFI). The advisory recommended that each instrument be tested for RFI. Prior to trial, Thayer filed a request for discovery relating to the issue of RFI testing, and his case was consolidated with several other DWI cases for purposes of an evidentiary hearing.

Testimony at the evidentiary hearing focused on procedures that the Anchorage Police Department had used in testing for RFI. The municipality established that between October and December of 1982, in response to the Smith & Wesson RFI advisory, Anchorage Police Officer John Reed tested the municipality’s breathalyzer instruments. However, Officer Reed apparently did not strictly adhere to the testing procedures recommended by Smith & Wesson. Accordingly, prior to trial, Thayer moved to suppress his breathalyzer test results, arguing that the municipality’s RFI test was inadequate and untimely and therefore failed to meet foundational requirements for admission. District Court Judge Warren A. Tucker initially granted Thayer's motion, finding that no scientific evidence was presented to validate Officer *724 Reed’s RFI testing procedures. The municipality subsequently filed a motion for reconsideration, and an additional eviden-tiary hearing was held on February 9,1983.

At the February hearing, Dr. Richard Jensen, a radio frequency interference expert from Minnesota, testified generally about his experience with RFI and breathalyzers. Dr. Jensen further testified that he had tested the municipality’s breathalyzers and that his tests indicated that RFI was not a problem with the instruments at their present location. Based on Jensen’s testimony, Judge Tucker vacated his original suppression order. Thayer’s breathalyzer result was admitted against him at his DWI trial.

ADEQUACY OF RFI TESTING

On appeal, Thayer first challenges the trial court’s denial of his motion to suppress. He contends that his breathalyzer result was inadmissible because the municipality did not meet the foundational requirements of AS 28.35.033(d). At the time of Thayer’s arrest, AS 28.35.033(d) 1 provided:

To be considered valid under the provisions of this section the chemical analysis of the person’s breath shall have been performed according to methods approved by the Department of Health and Social Services_ If it is established at trial that a chemical analysis of breath was performed according to approved methods by a person trained according to techniques, methods and standards of training approved by the Department of Health and Social Services, there is a presumption that the test results are valid and further foundation for introduction of the evidence is unnecessary.

At the time of Thayer’s arrest, 7 AAC 30.050(a) provided, in pertinent part:

CALIBRATION OF INSTRUMENTS
(a) Each breathalyzer instrument shall be calibrated in accordance with the manufacturer’s instructions at intervals not to exceed 60 days.
(b) At the time of calibration the instructor performing the activity shall
(1) enter the date and calibration information in the Breathalyzer log;
(2) forward to the department a certificate containing the date of calibration, the .serial number of the instrument and its location.

In September 1982, more than a month before Thayer’s DWI arrest, Smith & Wesson issued the RFI advisory at issue in this case. The advisory states, in relevant part:

Since the inception of evidential breath-testing for alcohol, changes have taken place in communications equipment used by law enforcement agencies. Radio transmissions, especially within the last few years, have increased significantly in number, broadcast frequencies, and power levels, resulting in an increase in the potential for radio frequency interference (“RFI”) in the normal operation of electronic equipment. This includes some breath-testing equipment. However, because the “window of susceptibility” to RFI during the test cycle of Breathalyzer instruments is narrow— limited to a coincidence of specific frequencies and signal strengths during a restricted time interval — it should not be assumed that past test results were necessarily distorted even in the presence of some radio frequency energy.
Earlier this year Smith & Wesson issued a customer advisory outlining a potential problem with the Breathalyzer Model 1000’s susceptibility to radio frequency interference. Preliminary tests conducted at that time on the Breathalyzer Models 900 and 900A did not indicate a problem. Continuing investigation now suggests this early series of breath-testing instruments may be affected in an unpredictable manner by various frequencies and power levels. Further, the extent of sensitivity to particular frequencies and *725 particular power levels will vary from instrument to instrument. Since test conditions were representative of some police environments, the possibility exists, although unlikely, for higher or lower than normal test results. Therefore each instrument should be tested on location in accordance with Test One and Test Two procedures outlined in this advisory.

Once the radio frequency interference tests as outlined in Test One and Test Two have been completed, subsequent testing would not be required unless one of the following conditions occur:
1. A change in the department’s radio operating frequencies or power output.
2. A change in the position, location, or type of base-station antenna.
3. Repair or calibration of the instrument.
4. A change in the operating location or general position of the instrument.
5. A change in the general background RFI environment of the instrument. [Emphasis added.]

Thayer specifically relies on the portion of the Smith & Wesson advisory that recommends retesting for RFI after “[r]epair or calibration of the [breathalyzer] instrument.” Thayer points out that former 7 AAC 30.050(a) required calibration of breathalyzer instruments at intervals not to exceed sixty days.
