The positioning specified in this clause is used for the test cases titles as tests for Browsing Mode with Hand Phantom. The characteristics of the Hand Phantom are specified in Annex A.2.2. Browsing mode is used to simulate user cases were the DUT is held in hand, but not pressed against ear e.g. web browsing and navigation. The DUT shall be mounted in a suitable hand phantom and oriented such that the DUT’s main display is tilted 45 degrees from vertical. Devices with a cover piece are tested cover open. Narrow DUT

This procedure is suitable for use with all DUTs narrower than 56 mm. The alignment Tool A in Figure is first used to measure the distance between the bottom of the DUT and the centre of its navigation key. The DUT is then positioned in accordance with ruled markings on a palm spacer to data mode hand phantom.

  1. Place the DUT on the DUT alignment Tool A. Record the chin length from the scale at the bottom of the alignment tool.
  2. Record the location of the navigation key (or the “2” key, if no navigation key is present) on the side ruler of the DUT alignment tool A. The key’s centre is used as the reference.
  3. Add the two readings from Step 2 and 3 together. If the sum is less than 30 mm, then use 30 mm location on spacer instead.
  4. Place the DUT on the right-hand or left-hand narrow data palm spacer and align the side of the DUT with the side wall of the spacer. The bottom edge of the DUT shall be placed on the narrow data palm spacer at the ruling corresponding to the value obtained in Step 4.

Make sure that the index finger is in contact with the back of the DUT. If the device is very narrow and/or thin, it may occur that the middle finger does not curl tightly enough to contact the DUT. In such case, in order to ensure consistent test results, no attempt should be made to force the fingertip to contact the DUT. Touch fastener material may be used to maintain the DUT in the desired position.

NOTE: Use left-handed (mirror-imaged) spacers with left-handed phantoms. PDA

This procedure is suitable for use with DUTs of width 56-72 mm. The positioning of the DUT in the PDA hand for data mode is identical to that for speech mode described in Subclause
