The Type I personal Phaser is issued to all Starfleet officers on board the USS Vangaurd. It fits neatly into a pocket sewn into the inside of the waistband of the regular duty uniform.

The power levels available to the Type I phasers are designated 1 to 8.

Setting 1: Light Stun; discharge energy index 15.75 for 0.25 seconds, SEM:NDF ratio not applicable. This setting is calibrated for base humanoid physiology, and causes temporary central nervous system (CNS) impairment. Subjects remain unconscious for up to five minutes. Higher levels of reversible CNS damage result from repeated long exposures. The discharge energy index is related to RNE protonic charge levels. Standard median-density composite structural material samples are not permanently affected, although small vibrational warming will be detected. A standard composite sample consists of multiple layers of tritanium, duranium, cortenite, lignin, and lithium-silicon-carbon 372. A standardized damage index is derived for setting comparisons; each whole number represents the number of cm of material penetrated or molecularly damaged. The damage index for this setting is zero.

Setting 2: Medium Stun; discharge energy 45.30 for 0.75 seconds, SEM:NDF ratio not applicable. Base-type humanoids are rendered unconscious for up to fifteen minutes, resistant humanoids up to five minutes. Long exposures produce low levels of irreversible CNS and epithelial damage. Structural materials are not affected, though higher levels of vibrational warming are evident. The damage index is zero.

Setting 3: Heavy Stun; discharge energy 160.65 for 1.025 seconds, SEM:NDF ratio not applicable. Base humanoids remain in a sleep state for approximately one hour, resistant bioforms for fifteen minutes. Single discharges raise 1 cc of liquid water by 100íC. Structural samples experience significant levels of thermal radiation. The damage index is 1.

Setting 4: Thermal Effects; discharge energy 515.75 for 1.5 seconds, SEM:NDF ratio not applicable. Base humanoids experience extensive CNS damage and epidermal EM trauma. Structural materials exhibit visible thermal shock. Discharges of longer than five seconds produce deep heat storage effects within metal alloys. The damage index is 3.5.

Setting 5: Thermal Effects; discharge energy 857.5 for 1.5 seconds, SEM:NDF ratio 250:1. Humanoid tissue experiences severe burn effects but, due to water content, deep layers will not char. Simple personnel forcefields are penetrated after five seconds. Large Away Team fields will not be affected. The damage index is 7.

Setting 6: Disruption Effects; discharge energy 2,700 for 1.75 seconds, SEM:NDF ratio 90:1. Organic tissues and structural materials exhibit comparable penetration and molecular damage effects as higher energies cause matter to dissociate rapidly. Familiar thermal effects begin decreasing at this level. The damage index is 15.

Setting 7: Disruption Effects; discharge energy 4,900 for 1.75 seconds, SEM:NDF ratio 1:1. Organic tissue damage causes immediate cessation of life processes, since disruption effects become widespread. The damage index is 50.

Setting 8: Disruption Effects; discharge energy 15,000 for 1.75 seconds, SEM:NDF ratio 1:3. Cascading disruption forces cause humanoid organisms to vaporize, as 50% of affected matter transitions out of the continuum. The damage index is 120; all unprotected matter is affected and penetrated according to depth/time.
